As you can see in attached GIFs, bookmarks in superior bookmark bar can be moved easily just as should be, but in additional bookmark field they can't be moved at all. I try to move them, but there is no "insert here" line appearing, and after I release my left mouse button it somehow opens the bookmark the cursor was on at the release moment. No matter fullscreen or windowed mode. I have custom "animated Codama" theme and some add-ons like "Midnight Lizard" and "uBlock", but disabling any of them doesn't help. Any ideas?
