Fix #112462: Panel buttons remain active after redrawing

Browse Source 
This seems to be an issue deep inside UI drawing code. The nodes render
the panel button in the correct place,
but it doesn't correctly update the button state after a redraw, unless
the mouse is moved. The button is still in a `BUTTON_STATE_HIGHLIGHT`
state after drawing, and a mouse press will trigger it regardless of
where the mouse cursor actually is.

A common hack to force a reset of the button state is to add a fake
mouse move event using `WM_event_add_mousemove`.
