An update on this, the persistent alert dots only go away once I have had a new alert for that thread and read it. This clears the dot for both alerts at once.This week I've started seeing alerts for a post, where the white dot doesn't clear after I've viewed it. I've tried refreshing, loading the thread then refreshing again, lingering on the page scrolling to the end/top etc.
It always goes away in a little bit but I can't seem to trigger it. It's happened about 4 times.
