I just realized that more than MATE Terminal is affected.  For
example, if I'm using firefox on a long web page, click the scrollbar
and quickly scroll through the page, then sometimes it behaves like
after a bit I've released the mouse button: Instead of scrolling,
the mouse (which is now outside of the scroll bar area) starts
highlighting text instead.
