Hi Team, 

Currently, there is no designated event that is being fired when selecting an already selected item in the PanelBar component. I would like to have an event that is being fired in such a use case.

In React and jQuery, the PanelBar component seems to be firing an event in such cases:

- jQuery: https://demos.telerik.com/kendo-ui/panelbar/events
