On Mac when the mouse goes over the map the fling stops immediately. This doesn't happen in Chrome. The fling continues until it has no intertia left.

I can reproduce. Not sure offhand what's causing it, but most likely the wheel events are getting split into separate transactions/blocks with their own hit-tests, so as soon as the mouse is over the map the wheel events start going there, and the map's zooming feature takes over and cancels the wheel-scrolling. By contrast, in Chrome, all the wheel events in the "fling" are part of a single transaction and so this doesn't happen.
Just skimming the relevant Gecko code (stuff that calls this function and nearby codepaths) I would expect Gecko to behave the way Chrome does, so we can look into why it's not.
P3 for now unless it happens on other websites too.
