fractal shows old rooms in sidebar
During fractal's initial sync, it displays old rooms in the left sidebar (rooms that I have long since left). Normally, it removes these old rooms and displays my current list of rooms immediately after its initial sync.
But sometimes, after fractal's initial sync, it just leaves all these old rooms present in the sidebar instead of removing them. I think it might be a regression from 4.2.1 since I don't remember seeing this issue until recently. It's not easy to reproduce: it happens perhaps once every 10-20 times I open fractal.
