I have noticed that whenever you want to upload multiple photos at once, using this React Upload Component & Events - KendoReact Docs & Demos (telerik.com) component the previews of the images uploaded bounce/ shake around. I've tried this on multiple browsers and they all have the same bouncing effect for the image previews. For a single photo it doesn't do it but once multiple images are added, it will do it.

When typing into a date picker and trying to type Feb 29th, 2024 (or any other leap year ofc) the date is updated incorrectly by the kendo date picker validation. As the user types the year their previous entry of 29 is updated to 28. This should update check should probably not occur until the user is done updating the input. If there is some fix or workaround we can do on our end to resolve this issue please let us know

Here's a video of the bug in our application

However, I was also able to reproduce the exact same behavior even in the documentation:

Hi! 

I have noticed that keyboard navigation doesn't work in the filter editor components inside the Filter component

Reproduction:

1. Open https://stackblitz.com/edit/react-rvwjsm?file=index.html
2. Choose "name" or "price" from the first dropdown
3. Type anything in the input field
4. Try to change the cursor position in the field using arrow keys - doesn't work

 Is there a way to enable it or go around it? 

Issue 1:

I've implemented insert table tool in the editor and I'm setting some states on editor blur. The bug appears when the editor is focused and I try to add a table. When I select the rows and cols from the dropdown  and click to insert the table the editor blur is called my setStates are called and somehow the table insertion doesn't happen. In order to add the table I should not focus the editor and I have to click on the insert table button and select again the cols and rows.

Issue 2:

In the same editor I've added tableResizing plugin. The bug appears when I already have a table in the editor and open the insert table dropdown to add a new one. In that moment when the dropdown is still opened I hover over some of the already inserted table cells borders the insert table dropdown is closed.

Issue 3:

When the editor is controlled we have undefined as initial value and then we type something or try to add table for example the editor crashes and throw an error `Uncaught RangeError: Applying a mismatched transaction`. Even though the value type allows undefined EditorProps.value?: string | Node | undefined. It works fine though if the initial value is empty string.

Package
"@progress/kendo-react-editor":"^5.11.0 | 5.12.0"

Minimal reproduction
I'm providing an vite + react + ts project. Steps to run the project:
npm install
npm run dev

It's reproducible in the provided examples in StackBlitz from Kendo, but the editor packages are not always resolved with turbo package manager. I guess it's the same issue as https://github.com/telerik/kendo-react/issues/1530

To demonstrate:

1. Open your simplest interactivity/selection demo, which is not grouped, in StackBlitz. See: https://www.telerik.com/kendo-react-ui/components/grid/interactivity/selection/

2. Add the Grid's group prop. To demonstrate the bug nothing else needs changed

<Grid group={[]} ...

3. Run demo, scroll down and pick a row.

4. Observe the grid scrolls to the top and you cannot see your selected row unless you scroll back.

Hi,

The first render of a DatePicker component with an onOpen prop throws an error: Unknown event handler property `onOpen`. It will be ignored.

Reproduction:

1. Open https://stackblitz.com/edit/react-xje2zdjc?file=app%2Fapp.tsx

2. The error will appear in the console

Expected behavior:

No errors in the console

The examples from https://www.telerik.com/kendo-react-ui/components/intl/i18n/loading-data work with cldr* packages up to version 47.0.0. The Current version 48.0.0 causes an error:

Please see the example - https://codesandbox.io/p/sandbox/silly-wind-tpfg8n

When column "Unit Price" is locked, while moving the horizontal scroll bar, the group header is sticky (expected behavior), but the group footer is not sticky (wrong behavior).

I'm submitting a...

• Bug report

Current behavior

Timepicker component in adaptive mode behaves differently in version 11.0.0 (and above) compared to version 10.0.0 (and above):

• "Set" button sets value but does not close popup - one more click needed
• "NOW" button scrolls to current time, but does neither set value nor close the popup - two more clicks needed
• in the top right corner there is a button with check icon which does the only thing - closes the popup (the same as "Close" button) - it is confusing

Expected behavior

We would expect the same behavior as in the 10.0.0:

• "Set" button sets value and closes the popup
• "NOW" button scrolls to current time, sets value and closes the popup
• there are no two buttons with the same functionality

Minimal reproduction of the problem with instructions

1. Please run following link: https://stackblitz.com/edit/react-j3smansk?file=app%2Fapp.tsx,package.json and adjust app container width so that the timepicker popup is rendered in the bottom half of the screen, allowing both the popup and the editor to be visible at the same time. 
2. Repeat previous step for following link: https://stackblitz.com/edit/react-ukfuqrdy?file=package.json,app%2Fapp.tsx
3. As you can see in "app.tsx" examples are very the same (taken from https://www.telerik.com/kendo-react-ui/components/dateinputs/timepicker/adaptive-rendering), only versions of kendo-react components in "package.json" are different
4. Observe situations described in Current behavior and Expected behavior sections

What is the motivation or use case for changing the behavior?

We would like to upgrade to 11.0.0 but we do not like this behaviour because it is disturbing, confusing and requires more clicks (time) to work with it.

Environment

Browser:

• Chrome (desktop) version 138.0.7204.50 (Official build) (64-bit)
• Firefox version 140.0 (64-bit)
• Edge Version 137.0.3296.93 (Official build) (64-bit)

System:

• TypeScript version: KendoReact demos page version
• Node version: KendoReact demos page version
• Platform: Windows 10

When clicking on a resize handle (without dragging), the window unexpectedly shrinks.

Steps to reproduce:

1. Open a Window component
2. Click on any resize handle without dragging

Expected behavior: The window size remains unchanged when clicking a resize handle without dragging.

Actual behavior: The window shrinks.

Reproducible on the demo page: https://www.telerik.com/kendo-react-ui/components/dialogs/window

Hi, 

After pasting a value into the input box of the DatePicker I am then unable to clear it. The value of the DatePicker is correctly set to null, but the value displayed in the input box is unchanged.

Reproduction steps:

1. Open the grid filtering demo,

2. Copy any of the date values from the grid, e.g. 9/20/1996, and paste it into the "First Ordered On" filter,

3. Clear the filter using the clear button.

Result:

The value remains in the input box.

Expected behaviour:

The value should not be visible in the input box.

Hello

Localization messages for ColorPicker popup Apply/Cancel are missed.

Option to hide does not work flatColorPickerSettings={{showButtons: false}}

When there are many items in the menu, the height should not exceed the page size. Now the scroll is not displayed.

It refers to version 9.1.0, version 8.5.5 works fine

Thank you

in latest v9.3.1 it appears GridFilterCell isn't passing properties shaped as 'isRequired' on DatePicker popupSettings 

this does seem to be a regression because i just recently noticed it in latest upgrade which we need for other bug fixes.

i pursued patching myself by populating animate in GridFilterCell.mjs which seemed to work but then i got warning for the next required property "appendTo". however, populating appendTo yields warning "Warning: Failed prop type: Invalid prop `appendTo` supplied to `Kendo React Popup`. Validation failed." so it's not easily reconcilable that way... therefore i tried removing isRequired on all 3 DatePicker popupSettings properties which of course avoided warnings and i didn't see any negative side effects.

here is a codesandbox repro minimally tweaked to include a date field from kendo grid's "getting started" demo: https://codesandbox.io/p/sandbox/cool-sanne-d4tp85

admittedly this is just a warning but it does create unnecessary noise in browser debug which detracts from issues truly requiring attention during development.

Hi, there is a problem with filter filter popups in Data Grid.

Steps to reproduce:

1. Go to https://www.telerik.com/kendo-react-ui/components/grid/filtering

2. Open the date filter popup  in the "FirstOrderOn" Column and click on any date

3. Open and close the filter combo in "Disconinued" column couple of times. 

Actual Behavior
On version 9.1.0 besides Opening the "Disconinued" filter combo, the date popup also openes. On version 8.5.0 seems to work fine

Expected Behavior
Only the popup from "Discontinued" column should be Opened / Closed
