Dragging a bookmark to be the last one doesn't work most of the time
You can't drag a nautilus bookmark to the very bottom, making it the last bookmark. In most cases that makes it the one before the end, but not the last one. Very rarely it succeeds in making it the last one. I don't know whether this is a race condition or something. See the video attached.
