Especially since I recently got a MX Master 3 mouse with the best scroll wheel
ever™, the broken increase/decrease in numberfields with spinners in Firefox
irked me more than ever. As a new ExtJS, which would had this fixed, seems not
like an option happening anytime soon I finally got to a workaround.
It seems hacky, but effectively it just preserves the casing for the
'DOMMouseScroll' event, like it'd be done for vendor specific events.
As other browsers seem to be OK without that keep them that way, to reduce
regression possibilty as much as possible.
I tested all scroll bars I could immagine in 3 minutes, please holler if
something still broke.
