Bug of mouse-face?

[Kenichi Handa]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Please evaluate the following codes in *scratch*.

(font-lock-mode -1)
(set-face-attribute
 (make-face 'box-released) nil
 :box '(:style released-button :line-width 4))
(set-face-attribute
 (make-face 'box-pressed) nil
 :box '(:style pressed-button :line-width 4))

(insert (propertize " a " 'face 'box-released 'mouse-face 'box-pressed)
        " "
        (propertize " b " 'face 'box-released 'mouse-face 'box-pressed)
        " "
        (propertize " c " 'face 'box-released 'mouse-face 'box-pressed)
        " "
        (propertize " d " 'face 'box-released 'mouse-face 'box-pressed))

When you move mouse from right to left on the line of "a" to
"d" buttons, mouse-face works correctly (i.e. when mouse is
on a button, the button is displayed with box-pressed face.
But, when you move mouse from left to right, after "a" is
displayed with box-pressed face, it doesn't change even if
mouse moves right off from "a", and buttons "b" to "d"
doesn't change face even if mouse is on it.

Emacs 21.3 and RC don't have this problem.
