bug#16552: 24.3.50; regression: mouse-face does not turn off when move mouse away

[Drew Adams]

This is with my setup.  I don't yet have a recipe from emacs -Q.

In this build:

1. If I move the mouse over multiple mouse-face zones of text, in a
buffer such as *Backtrace*, it behaves normally: the zone under the
mouse is highlighted, and other zones are unhighlighted.  That is,
when I move the mouse away from a zone it is unhighlighted.

2. But if I then click the title bar of another frame, and then move the
mouse over zones in the original frame, as the mouse moves into a zone
it is highlighted (which is normal), but as it moves out of a zone it is
not unhighlighted.  The effect is to highlight more and more zones as I
move the mouse.

(This is a regression.)

Are you still seeing this problem?  If so, can you give a recipe
starting from -Q?

No, I don't think so.  Trying the recipe now I do not see
the problem.  Please close.  Thx.
