Steps to reproduce:
1. Make a good post
2. Have someone reply to it
3. Have them delete the reply
4. Click the orange circledot in the top left corner
5. Dismiss any visible replies one by one
6. Navigate elsewhere
7. Observe the circledot is still teal, as if you have an un-dismissed reply
8. Click the circledot and observe that there are no posts shown
9. Click 'dismiss all'; now the circledot will be grey
