Scroll position much lower when going back to topic list from thread

Mobile, iOS Safari

Seeing this a lot lately, where I’ll tap into a thread and then tap the browser’s back arrow and I’m not in the same scroll position I was when I entered the thread. I’m much further down the topic list.

Perhaps related to the new plugin for tweets changing the page alignment after rendering?

Doesn’t sound like it, this is about the scroll position of the topic list page.
