Weird that no one else can reproduce this. It's 100% consistent here, even after clearing the cache. It only happens on that one thread, all others are fine.

We'll chalk it up to more C9+IE8 weirdness. C9 and IE8 are a terrible combination at the moment. C9 manages to crash IE8 (which fortunately brings down only the one tab) about ten times a day, because of simple actions like selecting text or scrolling. No other site does that in IE8, so I'm not sure what's causing it.

No, we can reproduce the issue, albeit in different browsers.

I've been getting around it by copying and pasting the link of the page number link, just right click and copy.
