Description Arthur 2019-02-28 13:24:17 PST

Something similar to https://bugs.webkit.org/show_bug.cgi?id=193860 or https://bugs.webkit.org/show_bug.cgi?id=193215 but only main page case embedded <iframe> and that iframe uses history navigation. So swiping back freezes the page for a few seconds. Tapping back button is Safari works fine and the page is accessible immediately.

Do you really mean iOS 12 Beta 3? (it was a thing, but many months ago).

Your case sounds exactly like 239720; do you have a site that reproduces?

Oh, sorry, I meant iOS 12.2 Beta 3 :-(

I don't have a repro though. I was just exploring putting our website (m.vk.com) into iframe and saw that issue. Not sure if it's specific to our website.

It works fine when in main window though.
