Windows: Fix bug where stale mouse button state could get sent to windows after a window move

Browse source 
handlePositionChanged() is called when the window changes z-order, which
may cause a new mouse event to be synthesised if the mouse is over the
window after the z-order is updated. In this situation, we may not have
received a mouse up/down/move event to update the current modifier
flags, so we need to update them ourselves.
