Do the developers reply here? I hope they're aware of the issue. Really good browser that I don't want to swap away from

It used to work just fine but some new update broke it. Now you can't scroll through a folder that has many bookmarks (no arrow either) and what would be the middle of your bookmarks is now show as the top of the list. It's completely broken.

Is there a way to revert without losing the browser settings (not the bookmarks) and are the devs aware of this issue?
