bug#57020: 29.0.50; Mouse wheel stops working

[Michael Heerdegen]

Hello,

I have been seeing this for a while now (maybe two weeks or a bit more,
not sure when it started exactly):

After starting Emacs everything is good.  But after a while, the mouse
wheel stops working.  That is, mouse-4 and mouse-5, with and without
modifiers, are not recognized.  In all buffers and windows, scroll-bar,
mode line, everywhere.  C-h k shows nothing because no event is
registered.

When that happens the mouse wheel still works normally in other X
windows or the window manager or in a newly started Emacs session.

This is under X and Openbox.

TIA,

Michael.
