Temporary bubble hack for new insets

Offset the view instead of using setForwardedInsets which doesn't
work anymore with the new insets system. That should resolve
itself automatically once we migrate Bubbles off VD.

Also, make sure we don't consider a window to be animating when
being insets controlled since it breaks syncInputWindows, for
example.
