Users have reported that ctrl+pinch behaves very differently since DesktopZooming was enabled. I can replicate the problem on Windows. STR: - visit any website (e.g. this bug) - ctrl + pinch and observe behavior - reset the zoom - set `apz.allow_zooming` to false - refresh the page - ctrl + pinch again and observe behavior For me, ctrl + pinch becomes extremely fast and makes it hard to incrementally change the reflow zoom when `apz.allow_zooming` is enabled. Users have reported [laggy behavior](https://support.mozilla.org/en-US/questions/1315366). I think it would be great if ctrl+pinch could behave the same as it does when DesktopZooming is disabled.
