I think this has always worked this way (certainly it does so on 78). I don't know if there's a good way of avoiding this, or if we want to. Up to the bookmarks team. The same thing happens in the menubar menu (without the steps in comment #0 to add the button).

As Gijs says, it has always worked this way. I believe the reason the "empty" entry is there is so that there is a drop target so that if you want to drag/drop a bookmark to the folder, you have somewhere to drop it to.

I guess the only thing that might be different is making a sound, but I'd be surprised if that has changed.

Yes, it seems it is the same, way back on Firefox 55.0a1.
