Use Ctrl + Z to restore accidentally deleted bookmark

[Eeeee]

Edit Bookmark and DeIete Bookmark are too close to each other, so it's easy to contact them by mistake, and it's too troublesome to add an option of “Are you sure you want to delete the bookmark?
So I want to use Ctrl + Z to restore accidentally deleted bookmarks after accidentally deleting them and before clicking on a blank space. (For privacy, after deleting a bookmark, you can't use Ctrl + Z to restore the bookmark if you click on any blank space.)
