Fixes #4063
The hack that was added to avoid multi-click/keypress navigation from screwing with the animation, was causing some issues in particular when used inside of a Popup - e.g.
DialogHostwith the default style. I believe this is because thePopupapparently setsPopupRoot.IsHitTestVisible=Falsewhen it closes (See here). So in cases where the dialog reopens with the same content, their initial value forIsHitTestVisiblewill be false.To mitigate this issue, the hack (and the animation) is now skipped in case
TabControl.IsHitTestVisible == Falsewhen the animation is intended to occur. This avoids the issue the OP was experiencing, and still works in the "normal" use cases.
