The dropDownList supports several keyboard shortcuts as documented in https://demos.telerik.com/kendo-ui/dropdownlist/keyboard-navigation. However, when e.g. a KeyDown event is triggered (and handled) by the widget, its propagation is not stopped. This behavior can be witnessed in this DOJO.

In our case, we e.g. use dropDownLists inside dialog windows that can be closed via ESC. When pressing ESC while a dropDownList is focused, this not only closes the dropDownList (as expected), but also closes the dialog.

The dropDownList should stop the propagation of events that it handled.

Bug report

`DropDownListSelectEvent.dataItem` is undefined when using keyboard to select the optionLabel, but is defined when using the mouse

Reproduction of the problem

Steps

Dojo: https://dojo.telerik.com/IvEXOvUH

Make a selection (e.g. "Apples").
Select the optionLabel item.

Expected

The value of DropDownListSelectEvent.dataItem is the same whether the selection is made via keyboard or mouse (assumedly).
The value of DropDownListSelectEvent.dataItem is clearly specified in the API docs when selecting the optionLabel.

Actual
The value of DropDownListSelectEvent.dataItem is "Select an option…" when selecting with the mouse.
The value of DropDownListSelectEvent.dataItem is undefined when selecting with the keyboard.

Bug report

The value of a disabled DropDownList is not announced in the below screen reader -> browser combinations:

NVDA with Chrome
JAWS with Chrome

The value is correctly announced by NVDA in Firefox.

After testing the scenario with the ComboBox, the value was correctly announced in all screen reader -> browser combinations.

Reproduction of the problem

1. Open this Dojo example in Chrome with JAWS/NVDA - https://runner.telerik.io/fullscreen/ERAxiqIy/3
2. Click the Enable checkbox
3. Select a value from the DropDownList
4. Click the Enable checkbox again.
5. Focus the Checkbox and press the down arrow key.

Current behavior

The screen reader announces the disabled state of the DropDownList, but does not announce its value.

Note - the value of the regular select element below the DropDownList is announced.

Expected/desired behavior

The value of the disabled DropDownList should be announced in the above mentioned combinations.
