Unread indication of all tabs sometimes lost after a reconnect(s)
The (magenta) color in the tab list indicating that a tab has unread messages is sometimes lost after connectivity problems and reconnects. The color becomes normal (blue). The actual read state isn't lost: when switching to the tab, the separator line is where I left off, as expected.
I can only say this for MUC tabs, not sure about 1:1s.
