Pinned event changes not showing up in the room timeline

[anoadragon453]

Steps to reproduce

1. Have a room with some pinned messages
2. Unpin the messages
3. Don't see the m.room.pinned_events rendered in the timeline in any way (even if "Show hidden timeline events" is enabled)

Outcome

What did you expect?

To see the m.room.pinned_events state event rendered in the timeline as "@user:domain unpinned a room message." or similar. This is a supported feature, but there appears to be a bug preventing it from appearing.

What happened instead?

No mention of pinned messages in the timeline. However I can see the m.room.pinned_events state events in /devtools, and there are no pinned messages being shown in the room's UI. So my client definitely received the state events.

I've included some additional details (room ID, state event IDs) in the associated rageshake.

It turns out that if you turn the feature on in Labs, the events get rendered 🤦

Timo appeared had the same bug with the feature on however, so leaving this open for him to confirm.

Pinned messages are out of labs now - are you still getting this? I tried briefly and couldn't repro (although they did collapse slightly weirdly with a pin+unpin just collapsing to "Dave changed the pinned messages for the room." with no option to expand).

@toger5 says it was probably a fluke. So, closing.
