This has been a long standing issue on Windows without items on bookmark toolbar it is impossible to add by dnd on toolbar.
Also mentioned here #11034 (comment)

reason is that emptu bm toolbar is too narrow for being the drop area. A quick fix would be keeping the toolbar size even if empty not sure why we resized it to what it is now.

if blank space is a problem we could have a placeholder like "add or drag a bookmark from urlbar to populate this area"

[bradleyrichter]

We need a "drop zone" that would toggle the visibility of the BM bar during the drag action.

Possible @cezaraugusto ?
