bug#65129: 30.0.50; pinch gestures suddenly stops being recognised

[Visuwesh]

Unfortunately, I don't have a good reproducer for this but ever since
updating to master from the emacs-29 branch, pinch gestures in Emacs
frames suddenly stops being recognised.  When I do C-h k and pinch, or
view lossage, I see wheel-left and wheel-down events but no pinch event.

However, if I create a new frame and try to pinch there, it works just
fine.

I apologise again for the vague report, but I have nothing better to
offer.  So far, I haven't tried to reproduce this in an emacs -Q
session.
