Each tab in SplitEditor should have an unique id

[vagostep]

Hi, I'm using the Split Editor following the documentation.

I want to listen to the onFocus event so I can know which tab is the current focused.

Now, I'm always getting an Event that does not have any identifier to know which was the one who triggered the event

Right now is there a way to do this?

If not, can you consider to include?

Thanks!
