Some room names keep changing to `#` name only and back and forth

[erAck]

I have two rooms with name # only (well, sometimes), and only getting state events not messages. Apparently these "empty" rooms are a leftover from when I logged out of a Slack session they were initially synced from, and duplicates of newly synced same channels with a different room ID. The rooms keep changing name like this:

Wednesday, 10:40, Slack bridge bot changed the room name from #announce to #.
Wednesday, 10:40, Slack bridge bot changed the topic to "".
Wednesday, 16:02, Slack bridge bot changed the room name from # to #announce.
Wednesday, 16:02, Slack bridge bot changed the topic to "Description: Welcome Channel Updates".
Wednesday, 21:02, Slack bridge bot changed the room name from #announce-global to #.
Wednesday, 21:02, Slack bridge bot changed the topic to "".
Wednesday, 21:42, Slack bridge bot changed the room name from # to #announce.
Wednesday, 21:42, Slack bridge bot changed the topic to "Description: Welcome Channel Updates".

Such room name changes may also happen for the not abandoned but lively synced room if it bridges to the same Slack channel as the abandoned room exposing the behaviour.

I had the same issue, my pull request https://github.com/mautrix/slack/pull/23 fixes the problem on my instance

Perhaps https://github.com/mautrix/slack/commit/7e379049f1c0be2bb6d0b38eaff331f2eb000591 fixes it?
