Bookmarks incorrectly ordered after rearranging with drag and drop

Bookmark drag and drop is back to behaving unpredictably (it seemed to be fixed for a while and working for the last couple of years as far as I noticed at least).

For example, with the following ~/.config/gtk-3.0/bookmarks content:

file:///home/username/One  
file:///home/username/Two  
file:///home/username/Three  
file:///home/username/Four

dragging "One" to below "Four" (green insertion line appears below "Four") results in:

Two
Three
One
Four
