225514 2021-05-07 08:06:19 -0700 AX: Two finger swipe up does not read screen from top in home screen app 2021-05-07 08:06:28 -0700 1 1 1 Unclassified WebKit Accessibility Safari 14 All All NEW InRadar P2 Normal --- 1 ldebeasi webkit-unassigned webkit-bug-importer oldest_to_newest 1757867 0 427997 ldebeasi 2021-05-07 08:06:19 -0700 Created attachment 427997 Code Reproduction Using the two-finger swipe up gesture on iOS does not cause VoiceOver to speak the entire screen from the top when a website is running as a home screen app. Steps to Reproduce: 1. Open attached Code Reproduction on an iOS device. 2. With VoiceOver enabled, use two fingers to swipe up on the web content. You should hear VoiceOver correctly speak the entire screen from the top. 2. Add the code reproduction to the home screen. 4. In the home screen app, use two fingers to swipe up. VoiceOver will not speak the entire screen from the top. You should just hear a "pop" noise. Expected Behavior: I would expect that VoiceOver reads the entire screen from the top when using the two-finger swipe up gesture. Actual Behavior: VoiceOver does not read the entire screen from the top. Other Information: - Using the two-finger swipe down gesture (read screen from selected item) works as expected. - I can reproduce this on the iOS 14.6 developer beta. - This reproduces in a WKWebView instance as well. Please let me know if you would like a reproduction with that as well. 1757868 1 webkit-bug-importer 2021-05-07 08:06:28 -0700 <rdar://problem/77656721> 427997 2021-05-07 08:06:19 -0700 2021-05-07 08:06:19 -0700 Code Reproduction index.html text/html 462 ldebeasi PCFET0NUWVBFIGh0bWw+CjxodG1sPgogIDxoZWFkPgogICAgPHRpdGxlPlZvaWNlT3ZlciAtIFJl YWQgRnJvbSBUb3A8L3RpdGxlPgogICAgPG1ldGEgbmFtZT0idmlld3BvcnQiIGNvbnRlbnQ9InZp ZXdwb3J0LWZpdD1jb3Zlciwgd2lkdGg9ZGV2aWNlLXdpZHRoLCBpbml0aWFsLXNjYWxlPTEuMCwg bWluaW11bS1zY2FsZT0xLjAsIG1heGltdW0tc2NhbGU9MS4wLCB1c2VyLXNjYWxhYmxlPW5vIj4K ICAgIDxtZXRhIG5hbWU9ImFwcGxlLW1vYmlsZS13ZWItYXBwLWNhcGFibGUiIGNvbnRlbnQ9Inll cyIgLz4KICAgIDxtZXRhIG5hbWU9ImFwcGxlLW1vYmlsZS13ZWItYXBwLXN0YXR1cy1iYXItc3R5 bGUiIGNvbnRlbnQ9ImJsYWNrIiAvPgogIDwvaGVhZD4KICA8Ym9keT4KICAgIDxoMT5UaXRsZTwv aDE+CiAgICA8aDI+U3VidGl0bGU8L2gyPgogICAgPHA+Q29udGVudDwvcD4KICA8L2JvZHk+Cjwv aHRtbD4K
