Unread marker in the room list is not cleared

[MatMaul]

Steps to reproduce

Sometimes the unread bold + dot marker in the rooms list is not cleared, despite the fact that I did read the room, and the read marker in the room agrees.

Usually someone sending another event in the room fixes it.

Outcome

What did you expect?

No more bold + dot marker in the room list.

What happened instead?

They are still there.

Will you send logs?

Yes

The logs are for #synapse-dev room that is experiencing the trouble when I rageshaked.

Could you try this on Element Nightly or develop.element.io, there has been recent changes to appease things in that area and it could be that this has already been solved.

I have not been able to reproduce this issue

[MatMaul]

I can't really reproduce at will unfortunately, it just happens sometimes, and I couldn't pinpoint what was the actual trigger.

I am going to wait for next release, and if I can't spot the behavior anymore I'll close the bug.

I've also seen it fairly often on latest develop over the past few days, and @karlabbott was telling me the same thing just now.

[germain-gg]

The unread marker has had a regression in the past 24 hours and we will revert a change as part of matrix-org/matrix-react-sdk#9745 .
Would exclude yesterday and today's symptoms out of this issue.

I still believe @MatMaul 's issue has been fixed

I had this unread marker today using the current nightly.

May this be caused by threads? In the picture I scrolled up to a thread where I posted a message to. Means I must have read until there before. The unread marker still appears.

Reproduced this today: Room bolded and marked with notification dot in the room list when there are no unread messages (no unread threads either) (no jump to read arrow either)

Notification debug devtools output:
