Remote bookmarks aren't visible if :local-only, but still able to be navigated to
Remote bookmarks aren't visible in the file chooser when the local only flag is set. This makes some sense, however, it can cause some confusion when the remote folder is still able to be navigated to and used via gvfsd-fuse.
This has so far been most notable to me in Firefox, which uses the chooser with the local only flag for downloads. My SMB share bookmarks aren't visible, but I can still navigate to the shares in the chooser (using the normal "Other Locations") and save to them and have it work. The folders are essentially still usable in such a case, but the bookmarks are still not shown.
