### Steps to reproduce 1. In Firefox Nightly on Windows, open MLS map page: https://location.services.mozilla.com/map 2. Use the laptop touchpad scroll gesture to zoom in and out of the MLS map. 3. Lift your fingers from the laptop touchpad to stop zooming. ### Expected results The map should stop zooming. ### Actual results The map will zoom in and out, but when you lift your fingers from the laptop touchpad, the map will zoom in or out another zoom level. I can reproduce this on my Windows 10 laptop, but not on my MacBook Pro. This is a regression from allow_zooming bug 1620055, which is restricted to the Nightly channel.
