No notification for new comments in resolved questions

When a question is unresolved and someone adds a new comment to the question, I will either get a notification or the thread will have a little (1) next to the title.

However, when a comment gets added to a question that has been marked as “resolved”, there is no indication at all. The thread title is even still greyed out in the list as if there is no new activity.

Is this the intended behavior? I’ve had a few instances where the person asking the question has marked the thread “resolved”, but then had a few followup questions which were missed.
