In the DropDownList and ComboBox, virtualization only works when the popup is open. In both widgets, item navigation is functional by pressing down to select the next item in the list without opening the popup. However, when the end of the first page of results is reached, the selection goes back to the top of the first page of results instead of loading the second page via virtualization. This misleads the user in that it only presents a portion of the options available. This is also an issue for disabled users and accessibility.

https://demos.telerik.com/kendo-ui/combobox/virtualization

In both examples, holding down without opening the popup will never load more results.

We have had this issue in the past but it is a bigger issue now that we are focusing more on accessibility since users rely more heavily on keyboard navigation.

Reproduction of the problem

Scenario 1 Cascade with no pre-selected values.
Dojo example: https://dojo.telerik.com/uguXisaY/4

1. Select category “Baverages”, product “Chai” and order “Cunewalde”
2. Change category to "Condiments"

Result:
In R1 2019 the change event fires in disorder (Orders, Categories and Products)
In R3 2019 the change event fires for Categories and Products
In R3 2019 SP1 the change event fires only for Categories

Scenario 2 Cascade with pre-selected values
Dojo example: https://dojo.telerik.com/uguXisaY/10

1. Select category “Condiments”

Result:
In R1 2019 the change event fires for all ComboBoxes but twice for Orders
In R3 2019 the change event fires for all ComboBoxes
In R3 2019 SP1 the change event fires for all ComboBoxes but twice for Products

Scenario 3 Cascade in Grid with no pre-selected items
Dojo example: https://dojo.telerik.com/OpOkataY/9

1. Click Edit and select "BMW" in Brand.

Result:
In R1 2019 the change event fires for all ComboBoxes in inverse order: Year, Model, Brand
In R3 2019 the change event fires only Model and Brand in this order.
In R3 2019 SP1 the change event fires only Model and Brand in this order.

Scenario 4 Cascade in Grid with pre-selected items
Dojo example: https://dojo.telerik.com/OpOkataY/10

1. Click Edit and select "BMW" in Brand.

Result:
In R1 2019 the change event fires for all ComboBoxes in inverse order: Year, Model, Brand, but fires twice for Year
In R3 2019 the change event fires for all ComboBoxes in inverse order: Year, Model, Brand
In R3 2019 SP1 the change event for all ComboBoxes in inverse order: Year, Model, Brand, but fires twice for Year

Bug report

Dropping an image into the Editor's content results in the image being opened in the browser instead of being added to the widget's content. Reproducible in Chrome, IE and Edge. If there is existing content and the image is dropped in it, the image is added to the content as expected.

Regression introduced in 2019.2.619.

I would like to use drag and drop on treeList to reorder rows (with same parent) like on treeView or at least to have same events (drag, dragstart, dragend, drop), where I'll be able to change behaviour.

In cases when we have loadOnDemand set to true and we want to populate the value of the DropDownTree initially we need a way to check if this value is part of the available options. One possible solution is adding a valueMapper function similar to the one use in virtualization scenarios.

Spreadsheet with SASS based theme displays the array formula incorrectly in the formula bar: =Product(C3:C11)

Expected/desired behavior
Spreadsheet with SASS based theme should display array formulas with {} braces: {=Product(C3:C11)}
