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:

- React: https://www.telerik.com/kendo-react-ui/components/layout/panelbar/events/

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

Hi, Team!

Currently, when the PanelBar component is set to take up a specific percentage of its parent element(and the size of the parent element is also responsive) and the screen is resized, the dimensions of the PanelBar are not properly recalculated and the component causes changes in the page thus breaking the responsive design.
