Bugfix #25840

UI bug: when a button has an open menu, the menu closed on any 
mouse-over of other buttons in this panel. That's not too bad,
but it didn't check for whether the mouse was already inside the
menu itself (respecting safety region).

The bug showed error on zoomed in UI, using FPS presets, in case
the menu-button was drawing aligned with other buttons. A real
boundary case... :)
