The Pager keyboard navigation now includes the keys ENTER and ESC that allow to "enter" a detailed pager navigation as explained in https://docs.telerik.com/kendo-ui/controls/data-management/pager/accessibility/keyboard-navigation.

However, the key events bubble up the DOM. In our case, this causes unwanted effects like closing popups etc. (we close popups on ESC).

Shouldn't the propagation be prevented for keyboard events that are handled by the pager itself?

I've created a small DOJO which demostrates this behavior: Note how the keydown event of the outer container is always fired, even if ESC was pressed to navigate inside the pager.
