Loading gets stuck after navigating back from external link

In Safari on iOS (9.2.1), however, thinks work differently: Discourse loads surprisingly quickly, and shows the loading spinner. Sometimes, this completes quickly and you see the topic; but most of the time, you get stuck on the spinner until you reload the page.

Yes I repro this all the time on BBS. I don’t know that I have ever seen it outside Mobile Safari though.

@eviltrout can you have a look? Trivially reproducible on iPad when visiting external links and then going back.
