It occurs only on non-input HTML elements (like div or span with a tabindex attribute). The same issue is observed when element.scrollIntoView() is called from an iframe. I reproduced the issue on iOS (11.3.1), and with a locally built WebKit. It's very similar to the following closed bug : https://bugs.webkit.org/show_bug.cgi?id=158629 . 1429901 1 webkit-bug-importer 2018-06-04 14:25:55 -0700 <rdar://problem/40781035> 1477797 2 simon.fraser 2018-11-12 16:40:28 -0800 Was fixed by bug 186956. *** This bug has been marked as a duplicate of bug 186956 *** 341903 2018-06-04 08:17:27 -0700 2018-06-04 08:17:27 -0700 test case scroll-bug.zip application/x-zip-compressed 764 yann.armelin UEsDBBQAAAAIAEBYxEy0hbEG/wAAAKABAAAKAAAAY2hpbGQuaHRtbI1RPU/DMBDd+ysOM7QdmjAi iD0ABXUCCYTE6I9rYtWxUXJJyL/HdorUEQ++5+d779m66urp9fHj620PDbVOrKpUwElfc4aeiRVA 1aA0CUTYIknQjex6JM4GOu5u2fmKLDkUea/KXLK4/FNXKpgZepodcqakPtVdGLzZ6eBCd3e9z+ue AQhYDI0dgaSy3uAPZzcMrOGMOvnNQDwHPfRSOQR02KKnqozt55eogSh4CF47q0+cTdEiTIWJmtRa 1Ej7RfUwH8xmnTzX2+KYPDdbJl7siJBPQAGkCuNFzGL+z6T05aLXXXDu4Cl8WpxSwHtmwEYKxshd ukYcRXEQZR7IL1BLAwQUAAAACABGWMRM4NNwhd0AAABNAQAACwAAAHBhcmVudC5odG1sTZDBbsMg DEDv/QoPabdlyXqqUshl23mTtsuOFNyARCACt1n/fkBSaRdsy+L52fzh7eP1++fzHQxNbtjxEsBJ PwqGng07AG5Q6pLkdEKSoIyMCUmwC52bA9taZMnhUF/e1vD/j5cTCna1uMwhEgMVPKHPjMVqMkLj 1SpsavEEl4SxSUo6eXIofFg12rsHPwV9g0S33GQG7Wio33ddN/9uLl8qBudAh8WvCvYc83xIUQmm jHX6uazJ7oxJxtH6hsLcHwrmuEFhXyuoWv1L1z0e2cDblbY6FZV8tbZe7w9QSwECPwAUAAAACABA WMRMtIWxBv8AAACgAQAACgAkAAAAAAAAACAAAAAAAAAAY2hpbGQuaHRtbAoAIAAAAAAAAQAYAOV3 dLHi+9MB5Xd0seL70wEVZSRN4/vTAVBLAQI/ABQAAAAIAEZYxEzg03CF3QAAAE0BAAALACQAAAAA AAAAIAAAACcBAABwYXJlbnQuaHRtbAoAIAAAAAAAAQAYADUjzLji+9MBNSPMuOL70wF1YMe44vvT AVBLBQYAAAAAAgACALkAAAAtAgAAAAA=
