Observed result: moves the Voiceover cursor to the first child in the container. Oddly enough, simply putting an aria-label on the div results in the correct behavior: Action: calling the javascript focus() method on a div with a tabindex=-1 and an aria-label="foo" Expected result: moves the Voiceover cursor to the first child in the container. Observed result: expected result. Also notable is the fact that a div with a tabindex=-1 gets an accessibleRole value of Group (see Bug#148646: https://bugs.webkit.org/show_bug.cgi?id=148646) See attached test file for example and steps to reproduce. 1122306 1 webkit-bug-importer 2015-08-31 14:50:48 -0700 <rdar://problem/22507080> 1122831 2 cfleizach 2015-09-02 09:41:29 -0700 This is expected behavior. As soon as we see an object with "accessibility" attributes, we expose it to the AX hierarchy. if we see none of those attributes, then we'll hide the object to reduce tree bloat 260320 2015-08-31 14:49:26 -0700 2015-08-31 14:49:26 -0700 Test file that demonstrates unexpected behavior for calling focus() on div with tabindex=-1 vo-focus-bug.html text/html 2922 msadecki PCFET0NUWVBFIGh0bWw+CjxodG1sPgo8aGVhZD4KPHNjcmlwdCBzcmM9Imh0dHBzOi8vY29kZS5q cXVlcnkuY29tL2pxdWVyeS0xLjExLjMuanMiPjwvc2NyaXB0PgogIDxtZXRhIGNoYXJzZXQ9InV0 Zi04Ij4KPCEtLQpDcmVhdGVkIHVzaW5nIEpTIEJpbgpodHRwOi8vanNiaW4uY29tCgpDb3B5cmln aHQgKGMpIDIwMTUgYnkgY3B0dml0YW1pbiAoaHR0cDovL2pzYmluLmNvbS9yZXNvbWkvMy9lZGl0 KQoKUmVsZWFzZWQgdW5kZXIgdGhlIE1JVCBsaWNlbnNlOiBodHRwOi8vanNiaW4ubWl0LWxpY2Vu c2Uub3JnCi0tPgo8bWV0YSBuYW1lPSJyb2JvdHMiIGNvbnRlbnQ9Im5vaW5kZXgiPgogIDx0aXRs ZT5Wb2ljZW92ZXIgY3Vyc29yIHZlcnN1cyBLZXlib2FyZCBmb2N1czwvdGl0bGU+Cgo8c3R5bGUg aWQ9ImpzYmluLWNzcyI+CmRpdiB7CiAgYm9yZGVyOiAxcHggc29saWQgYmxhY2s7Cn0KZGl2OmZv Y3VzIHsKICBib3JkZXI6IDFweCBzb2xpZCBibHVlOwp9Cjwvc3R5bGU+CjwvaGVhZD4KPGJvZHk+ CiAgPGgxPlZvaWNlb3ZlciBjdXJzb3IgdmVyc3VzIEtleWJvYXJkIGZvY3VzPC9oMT4KICA8cD5D bGlja2luZyB0aGUgIk1vdmUgZm9jdXMiIGJ1dHRvbnMgc2hvdWxkIG1vdmUgZm9jdXMgdG8gdGhl aXIgcmVzcGVjdGl2ZSBjb250YWluZXJzIChkaXZzKSB0aGF0IGZvbGxvdy4gc3Vic2VxdWVudCBU QUIgb3IgVk8rcmlnaHQgYXJyb3cgd291bGQgbW92ZSBmb2N1cyB0byB0aGUgZmlyc3QgZm9jdXNh YmxlIGVsZW1lbnQgKGJ1dHRvbnMpIGluIHRoZSBjb250YWluZXIuIFRoZSBleHBlY3RlZCBiZWhh dmlvciBpcyBhY2hpZXZlZCB3aGVuIHVzaW5nIGEga2V5Ym9hcmQgdG8gbmF2aWdhdGUuICBIb3dl dmVyLCB3aGVuIFZvaWNlb3ZlciBpcyBlbmFibGVkLCB0aGUgVm9pY2VvdmVyIGN1cnNvciBtb3Zl cyB0byB0aGUgZmlyc3QgY2hpbGQgaW4gdGhlIGNvbnRhaW5lciAoZWl0aGVyIGEgYnV0dG9uIGlu IHRoZSBmaXJzdCBleGFtcGxlLCBvciB0aGUgSGVhZGluZyBpbiB0aGUgdGhpcmQuIEFuIGFyaWEt bGFiZWwgaGFzIGJlZW4gYWRkZWQgdG8gdGhlIHNlY29uZCBhbmQgZm91cnRoIGNvbnRhaW5lcnMs IGFuZCB0aGUgZXhwZWN0ZWQgYmVoYXZpb3IgaXMgb2JzZXJ2ZWQuIEFsbCBjb250YWluZXJzLCBh cmUgYW5ub3VuY2VkIGFzIGhhdmluZyB0aGUgImdyb3VwIiByb2xlLjwvcD4KPGRpdiBjbGFzcz0i dG9wIj4KICA8dWw+CiAgICA8bGk+PGJ1dHRvbiBjbGFzcz0ibW92ZS1vbmUiPk1vdmUgZm9jdXMg dG8gZGl2IG9uZTwvYnV0dG9uPjwvbGk+CiAgICA8bGk+PGJ1dHRvbiBjbGFzcz0ibW92ZS10d28i Pk1vdmUgZm9jdXMgdG8gZGl2IHR3bzwvYnV0dG9uPjwvbGk+CiAgICA8bGk+PGJ1dHRvbiBjbGFz cz0ibW92ZS10aHJlZSI+TW92ZSBmb2N1cyB0byBkaXYgdGhyZWU8L2J1dHRvbj48L2xpPgogICAg PGxpPjxidXR0b24gY2xhc3M9Im1vdmUtZm91ciI+TW92ZSBmb2N1cyB0byBkaXYgZm91cjwvYnV0 dG9uPjwvbGk+CiAgPC91bD4KPC9kaXY+CiAgPHA+VGhlIGNvbnRhaW5lciBiZWxvdyBoYXMgYSB0 YWJpbmRleD0tMS48L3A+CjxkaXYgY2xhc3M9ImRpdi1vbmUiIHRhYmluZGV4PSItMSI+CiAgPHVs PgogICAgPGxpPjxidXR0b24+bWVudSBpdGVtIDE8L2J1dHRvbj48L2xpPgogICAgPGxpPjxidXR0 b24gY2xhc3M9ImJhY2stdG8tdG9wIj5iYWNrIHRvIHRvcDwvYnV0dG9uPjwvbGk+CiAgPC91bD4K PC9kaXY+CiAgPHA+VGhlIGNvbnRhaW5lciBiZWxvdyBoYXMgYSB0YWJpbmRleD0tMSBhbmQgYW4g YXJpYS1sYWJlbC48L3A+CiAgPGRpdiBjbGFzcz0iZGl2LXR3byIgdGFiaW5kZXg9Ii0xIiBhcmlh LWxhYmVsPSJNZW51IDIiPgogICAgPHVsPgogICAgICA8bGk+PGJ1dHRvbj5tZW51IGl0ZW0gMTwv YnV0dG9uPjwvbGk+CiAgICA8bGk+PGJ1dHRvbiBjbGFzcz0iYmFjay10by10b3AiPmJhY2sgdG8g dG9wPC9idXR0b24+PC9saT4KICAgIDwvdWw+CiAgPC9kaXY+CiAgPHA+VGhlIGNvbnRhaW5lciBi ZWxvdyBoYXMgYSB0YWJpbmRleD0tMSBhbmQgYSBoZWFkaW5nIGZvbGxvd2VkIGJ5IGEgbWVudTwv cD4KICA8ZGl2IGNsYXNzPSJkaXYtdGhyZWUiIHRhYmluZGV4PSItMSI+CiAgICA8aDI+bWVudTwv aDI+CiAgICA8dWw+CiAgICAgIDxsaT48YnV0dG9uPm1lbnUgaXRlbSAxPC9idXR0b24+PC9saT4K ICAgIDxsaT48YnV0dG9uIGNsYXNzPSJiYWNrLXRvLXRvcCI+YmFjayB0byB0b3A8L2J1dHRvbj48 L2xpPgogICAgPC91bD4KICA8L2Rpdj4KICA8cD5UaGUgY29udGFpbmVyIGJlbG93IGhhcyBhIHRh YmluZGV4PS0xIGFuZCBhbiBhcmlhLWxhYmVsIGFuZCBhIGhlYWRpbmcgZm9sbG93ZWQgYnkgYSBt ZW51LjwvcD4KICA8ZGl2IGNsYXNzPSJkaXYtZm91ciIgdGFiaW5kZXg9Ii0xIiBhcmlhLWxhYmVs PSJNZW51IDQiPgogICAgPGgyPm1lbnU8L2gyPgogICAgPHVsPgogICAgICA8bGk+PGJ1dHRvbj5t ZW51IGl0ZW0gMTwvYnV0dG9uPjwvbGk+CiAgICA8bGk+PGJ1dHRvbiBjbGFzcz0iYmFjay10by10 b3AiPmJhY2sgdG8gdG9wPC9idXR0b24+PC9saT4KICAgIDwvdWw+CiAgPC9kaXY+CjxzY3JpcHQ+ CiQoJy5tb3ZlLW9uZScpLmNsaWNrKGZ1bmN0aW9uKCkgewogICAgJCgnLmRpdi1vbmUnKS5mb2N1 cygpOwp9KTsKJCgnLm1vdmUtdHdvJykuY2xpY2soZnVuY3Rpb24oKSB7CiAgICAkKCcuZGl2LXR3 bycpLmZvY3VzKCk7Cn0pOwokKCcubW92ZS10aHJlZScpLmNsaWNrKGZ1bmN0aW9uKCkgewogICAg JCgnLmRpdi10aHJlZScpLmZvY3VzKCk7Cn0pOwokKCcubW92ZS1mb3VyJykuY2xpY2soZnVuY3Rp b24oKSB7CiAgICAkKCcuZGl2LWZvdXInKS5mb2N1cygpOwp9KTsKJCgnLmJhY2stdG8tdG9wJyku Y2xpY2soZnVuY3Rpb24oKSB7CiAgICAkKCcudG9wJykuZm9jdXMoKTsKfSk7Cjwvc2NyaXB0PgoK PC9ib2R5Pgo8L2h0bWw+
