When a discussion is renamed, the old name is still displayed

Description:

When a discussion in a channel is renamed, the old name is still displayed in the body of the channel and in the discussion list on the right. The new name is only visible in the black sidebar on the left and in the discussion itself (see screenshots). I'm using the MacOS desktop app v3.8.6.

Steps to reproduce:

1. Create a discussion in a channel.
2. Enter the new discussion.
3. Click on the Room Information button, click Edit and rename the discussion.
4. Return to the channel and behold the old name still there.

Expected behavior:

I would naturally expect the new name to be displayed everywhere.

Actual behavior:

Relevant logs:

Start by reproducing the rename through the Room Information flow, then trace the channel body and right-hand discussion list where the old name remains visible. Done means the new discussion name appears in both locations as well as the sidebar and discussion view.
