patch 9.2.0946: GTK2/3: mouse move starts Visual selection after a dialog

Problem:  In GTK2/GTK3, when a dialog pops up while a mouse button is
          pressed, moving the mouse afterwards starts a Visual selection
          without any button being held down.
Solution: Forget about the pressed mouse button when another widget
          shadows the text area with a grab, since the button release
          event goes to that widget (Hirohito Higashi).

fixes:  #20907
closes: #21014
