Bastien Bouclet ad3feae490 MOHAWK: RIVEN: Fix crash when clicking on a marble with the mouse moving
In some cases a mouse moved event could be handled between the moment
the xtakeit script was queued and the moment it is executed (on the same
frame), causing the mouse position no longer to be over a marble
rectangle.

Fixes #10647.
