I haven't done extensive review of all input code on linux, but from what I
remember the event got dropped here:
https://cgit.freedesktop.org/xorg/driver/xf86-input-evdev/tree/src/evdev.c#n2720
It seems BTN_GEAR isn't clearly defined either.
Perhaps libinput does a better job at mapping the event, but we should consider
older guests. Spice agent is using rel-wheel events, and we never had issues
with it.
thanks
