"Search Locations" shows blank entries for unmounted GIO bookmarks
E.g. I have the following in ~/.config/gtk-3.0/bookmarks
:
sftp://foo@host/home/user host: ~
When unmounted, Settings -> Search -> Search Locations shows a blank list widget (no label or toggle) corresponding to the item (I determined this by counting the blank widgets vs. total unmounted GIO bookmarks, and experimentally mounting them then restarting Settings and re-checking).
Additionally, the Search Locations bookmarks list seems to be in random order, neither alphabetical nor corresponding to the order in the bookmarks file.
