So swiping back freezes the page for a few seconds. Tapping back button is Safari works fine and the page is accessible immediately. 1511240 1 webkit-bug-importer 2019-02-28 18:11:05 -0800 <rdar://problem/48496767> 1511283 2 thorton 2019-02-28 21:24:44 -0800 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? 1511284 3 nekr.fabula 2019-02-28 21:30:28 -0800 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. 1841110 4 bfulgham 2022-02-13 19:39:21 -0800 We can't seem to reproduce this issue. Please reopen if you can help us with additional test information.
