[Feature request]: Add details to tab click event

[liviakuenzli]

Request type

Request for enhancement of a component

Functionality

When clicking a tab-title, the tab-group is emitting an event. However, the event is lacking details; e.g. we do not know which item has been clicked. We would have to go through all the children and find the active one.

We propose to instead have the new activeIndex/tab-title element directly in the Event (event.details).

Is there a design proposal?

No

Link to design proposal file (optional)
