Thread view showing multiple copies of threads

[kieranlane]

Description

When I click on one of the threads in TAC, this one does open up the thread panel, but I see the thread listed twice.

Steps to reproduce

1. Click on a thread in TAC
2. It brings up the thread panel, showing the active threads
3. I see an entry twice or more.
4. Reading both of them keeps the white dots visible but also doesn't clear the notification from the TAC.

Anything else that would be useful to know?

Raising to link with element-hq/element-web#29070. See element-hq/element-web#29070 (comment) suggesting this maybe a server issue as the thread list is populated from a server API.

Would be good to have some request and responses or other server-side details to play with here.
