Double click forum icons to mark forum as read 2.1.0 Patch 1

Can't see any problems.
Can you describe the problem?

If there are many subforums and a new message in depth, then double-clicking on the forum icon shows that everything is working. But when you click the F5 button or refresh the page, you can see that subforums deeper than 2 knees are still not read

A new message in this subnode

I'm sorry, this doesn't work on older versions of xenforo.
In version 2.1.10 this is normal
Thank you
