Workaround :

The DropDownButton should support aria-label configuration through the `kendo-vue-intl` package. Currently, the value for the aria-label is set through the `text` prop and a hardcoded `dropdownbutton` word to it.

I have implemented Kendo Vue DropDownButtons in my project, and yesterday find out that "itemClick" event is not fired.

When I check the demo page - it also not working there.

"@progress/kendo-vue-dropdowns": "^3.5.0",

"vue": "^3.2.13",

Describe the bug
The DropDownButton's itemClick event doesn't work when you select one of its items with a tap on a touchpad.

To Reproduce

1. Open this StackBlitz example
2. Expand the DropDownButton and select an item with a mouse click - the itemClick event is logged in the event logger
3. Using a touchpad, select an item by tapping on the touchpad.
4. See the event logger - the itemClick event is not logged

Expected behavior
The itemClick event should be triggered consistently no matter if a mouse click or touchpad is used
