Fix a special case for button masks 

In certain situations it is possible that in a `Viewport` the same
mouse button is pressed twice in series without releasing it in
between.
In this case, focus stealing should happen to ensure, that the
mouse button is not sent unintentionally to the previously focused
Control node.
