Reading to the end of a thread doesn't remove it from Unread

This just started happening yesterday, I think -- recently, anyway.

If the last post in a thread is short, the red vertical progress thingy doesn't say n/n but rather n-1/n or n-2/n, and therefore this doesn't count as finishing reading. I can grab the red thingy and drag it down to n/n, but that doesn't stick and doesn't make the thread read.

The threads in question right now are HTML Blocks and Find Items in List.

Reloading should fix it.

I've had it happen to me, I just reloaded.

Reloading forum.s.b.e? Didn't work for me, even with a hard reload. :~( Thanks though.

Huh, it's not a problem for me
