fix: Issue 816 pfe tabs stop propagation (#819)

* fix: removing stopPropagation from pfe-tabs click and keydown events

Fixes #816

* updating the changelog

* should be currentTarget instead of event.target

event.target broke pfe-content-set. Using event.currenTarget is the right way to look for the selected tab.

* using event.currentTarget instead of foundTab
