Alternatively, maybe you can “flick” the maximized image up and it will dismiss it? Not sure if that would be easier.

Edit: That actually already works, at least on Android with FireFox.

This is the only annoyance I have with this app at the moment. I hope it gets fixed soon, as I already lost my scroll position on the home feed many times due to this

Similarly: All the meatball context menus (the three horizontal dots) have the same behavior. But those ones don’t really bother me as much since they have a large “Cancel” button right at the bottom.
