Observed behavior: If a user first does a touchpad multitouch swipe in a TextArea, and then clicks one of the tab buttons the SwipeView will not change. However, the tab bar button changes color to represent it's been clicked, and the currentIndex and currentItem are triggered and indeed do switch to the correct values. It seems like the view itself is not updated.

This only works with a multitouch swipe, and the proper behavior can be reestablished by clicking anywhere outside the field.

Expected behavior: when a tab button is clicked on, the swipe view changes.
