VM4197:1 ERROR DOMException: Failed to execute 'setAttribute' on 'Element': 'aria-disabled]' is not a valid attribute name.
When virtual is true for a multiselect and checkboxes are set to true, there is a bug which results in multiple items being selected.
To reproduce, one needs to scroll down a long list of items. The amount to scroll seems random but might have something to do with the itemHeight setting. When clicking directly inside the checkbox, two items are selected at once - the item selected, and one other seemingly random item. This does not happen if the click selection event happens inside the item, but not the checkbox.
I have reproduced this inside this code sandbox: https://codesandbox.io/p/sandbox/mystifying-shirley-2qxn32
Using the Editor component with Form Support, if I choose the style Heading 1 and type some letter.
I clean the value using only backspace key on the keyboard and the value of the form control is <h1></h1>.
This is reproductible on the demo : https://www.telerik.com/kendo-angular-ui/components/editor/forms/#toc-template-driven-forms
Expected result
Dear Kendo-Supportteam,
We are experiencing an issue with the Editor component.
It turns out that setting the iframe input to false causes the paste event to be triggered twice.
Once as documented before the valueChange event and once seemingly as the native paste event after valueChange.
There are multiple issues resulting from this.
It is quite easy to reproduce this from your event demonstration examples by just setting the iframe input to false and maybe also trying to call isDefaultPrevented in the respective paste event handler.
Kind Regards,
Hannah

When a detail row is used, the moment you expand one row and scroll, it automatically loads the last items from the dataset.
Ex expand row 1 - start scrolling, and it suddenly loads 5xx th row+;
When grouping is also enabled - expanding the detail row under one group, expands it under all groups.
The stackbliz is from the kendo demo page for virtualscroll (with the added detail row).
As demonstrated by the example of the current version and its screenshot, the title of the legend is black when using a dark theme:
Legend - Chart - Kendo UI for Angular (telerik.com)
The rest of the text is white which leads me to believe that this is a bug. This issue is not present when using a light theme.

When using kendoTooltip directive on the upload component - tooltips are positioned in invalid position somewhere on the app.
cancel, delete, retry tooltips.

The internal element has a calculated width - but it only grows in value if slider width changes (responsive or even in CSS with media queries etc).
It permanently stays at the largest size.

Repro steps:
Actual Result:
When pressing enter on the column menu present beside the "Contact name" column header of the table, Screen reader is no announcing the state of the the column as it is expanded or collapsed because of the role set as link.
Expected Result:
When pressing enter on the column menu present beside the "Contact name" column header of the table, screen reader should be announcing the state of the column menu as it is expanded or collapsed, role should be set as button with expand collapse functionality.
If you have a kendo grid table with some data over multiple pages and you go e.g. to the last page and then reload the data, resulting with less pages - the table is empty and you have to manually click on the first page to see the data. Here is a working example:
https://codesandbox.io/s/upbeat-lamarr-d67m8k?file=/src/app/app.component.ts
Step 1. Go to the last page
Step 2. Click on the button "'Reset data" <- you see no data
Step 3. Click on the first page <- You see the data
We are exporting an Excel from a treelist -> there are merged cells, and the table has lots of rows (~20k).
It's taking forever (it's unusable) and the reason is that there is an O(N^2) bug in the toXML function: each row adds a merged cell range, and the mergedCells array is scanned linearly for every new row.
I was able to fix this by adding a mergedCells hash (I would be happy to create a pull request).
Also, as a related issue, it would be nice to be able to change the compression level on the generated zip file, because the default again takes forever for large enough files.
If ComboBox is used in a form and its required, screen readers will not pick up this information since it is not passed on to the underlying input field.
The example a nice workaround, but a final solution should have this automatically implemented by the control.

Kendo version :
@progress/kendo-angular-buttons: 5.4.1
How to reproduce :
- Add a kendo dropdown button with some items
- Use appendTo='component' popupSetting
- Bind itemClick and close events
Stackblitz example : https://stackblitz.com/edit/kendo-dropdownbuttons-keyboardnavigation?file=app/app.component.ts
What happens :
- If you use arrows to navigate through items, is always skip one item.
- If you use enter or space to select item, the popup close and reopen immediately.
- If you prevent close as in the stackblitz example : enter and space will fire twice the itemClick event.
When setting the [zoom] value in TypeScript the drop down value does not reflect this and remains at the default of 125% even though the PDF is zoomed in/out.
Adjusting the zoom level using the buttons then "corrects" the issue and it displays the right value.
Fix ONE of the following:
Required ARIA children role not present: group, option
Element has no aria-busy="true" attribute
When an assistive technology encounters an element with an invalid ARIA attribute value, it might ignore the attribute or respond to it in an unexpected way. As a result, people who use assistive technologies might find the element difficult or impossible to use.
