Short description of error
Pretty much the same as #120587, just that it's still not fixed for my mouse, which is the Logitech MX Master 3.

Using the scroll wheel does not work (middle mouse button doesn't work either, but that may be an independent issue).

I added this debug print:

     seat->pointer_scroll.discrete_xy[1] = seat->pointer_scroll.discrete120_xy[1] / 120;

The output is this (note that I added a newline after each manual action, for the last section I scrolled a bit further):

Only if I move the mouse wheel very quickly, it is recognized by Blender currently.
