we should probably remove breadcrumbs from the list for rooms you have left

and instead re-discover them via Historical rooms, once that gets fixed

this is a bug :(

they should be at 50% opacity or in some conditions just not present at all in the first place.

If you change your mind on the opacity thing later and just remove the left rooms instead I'd like to be able to choose the behavior in settings.
