I've seen glimpses of it. Nothing mayor tho. When I switch back and forth between posts and different instances accounts on Jerboa comments form different posts first load up but then the content refreshes almost 1 second later.
I've had this happen a few times, it seems to happen when the page updates. Sometimes it'll show an entirely new post, sometimes it's a new post with the comments from the previous post.
Refreshing doesn't fix it, but going back a page sometimes does.
And I'm opening the posts in a new tab in Firefox mobile.
