wow, that's not at all where I was expecting it to be. TBH, when stuff like this does not work out of the box, my first instinct is not really to look for configuration settings about it, because it doesn't really make sense for me to have to configure this? I wouldn't even really imagine that the address bar gestures would have to be configured in the gesture settings even if I had known those existed.
but yes it appears that allows me to fix this manually. I do think that's a sorta weird UX though. :/
(I do recognize that the gestures being configurable is a good thing. What I'm not a fan of is just that the configurability means that they don't update automatically when I move the address bar to the top, and I'm left to find those gesture settings manually in order to do it)
