This markup example leaves much to be desired, b/c are a bunch of extraneous groups in the tree. - non-presentational LIs in-between the tree and the first-level treeitems. - extraneous non-presentational DIVs in-between the first-level items and second-level items. - irrelevant/extraneous @aria-owns relationships pointing to descendant nodes. That said, WebKit does a pretty good job of cleaning it up for the AX tree. The AXOutlineRows and AXLevels are exposed correctly. I think the only bug I noticed is that AXDisclosedByRow is <nil> on the second-level rows, so VO speaks "0 items enclosed". The ancestor hierarchy is intact, so we may just need WebKit to walk higher up the DOM tree to find the correct disclosing row. WebKit should normalize this scenario if possible. Hearsay: ~"JAWS+FF works with this example." If so, one or both of those is normalizing the invalid markup. 1005116 1 webkit-bug-importer 2014-04-29 14:31:48 -0700 <rdar://problem/16761069> 230420 2014-04-29 14:30:50 -0700 2014-04-29 14:30:50 -0700 test case invalid-nesting.html text/html 2073 jcraig PHA+Y29udGVudCBiZWZvcmU8L3A+Cgo8dWwgYXJpYS1vd25zPSJub2RlMSBub2RlMiBub2RlMyBu b2RlNCIgcm9sZT0idHJlZSIgYXJpYS1sYWJlbD0iQnJvd3NlIEhhbWxldCwgYnkgV2lsbGlhbSBT aGFrZXNwZWFyZSI+Cgk8bGk+CgkJPGEgaHJlZj0iIyIgaWQ9Im5vZGUxIiBjbGFzcz0iYnJhbmNo IiBhcmlhLWxhYmVsPSJBQ1QgSSIgcm9sZT0idHJlZWl0ZW0iIGFyaWEtc2V0c2l6ZT0iNCIgYXJp YS1wb3NpbnNldD0iMSIgYXJpYS1sZXZlbD0iMSIgdGFiaW5kZXg9IjAiIGFyaWEtc2VsZWN0ZWQ9 InRydWUiIGFyaWEtZXhwYW5kZWQ9ImZhbHNlIj4KCQkJPHNwYW4+QUNUIEk8L3NwYW4+CgkJPC9h PgoJPC9saT4KCTxsaT4KCQk8YSBocmVmPSIjIiBpZD0ibm9kZTIiIGNsYXNzPSJicmFuY2ggc2Vs ZWN0ZWQiIGFyaWEtbGFiZWw9IkFDVCBJSSIgcm9sZT0idHJlZWl0ZW0iIGFyaWEtc2V0c2l6ZT0i NCIgYXJpYS1wb3NpbnNldD0iMiIgYXJpYS1sZXZlbD0iMSIgdGFiaW5kZXg9IjAiIGFyaWEtc2Vs ZWN0ZWQ9InRydWUiIGFyaWEtZXhwYW5kZWQ9InRydWUiIGFyaWEtb3ducz0iYXJpYTEzOTg3MjY5 NjM4MjYiPgoJCQk8c3Bhbj5BQ1QgSUk8L3NwYW4+CgkJPC9hPgoJCTxkaXYgaWQ9IkFjY0RDMTM5 ODcyNjk2MzgyMSIgY2xhc3M9IlRyZWVWaWV3Ij4KCQkJPGRpdiBzdHlsZT0icG9zaXRpb246IGFi c29sdXRlOyBjbGlwOiByZWN0KDFweCAxcHggMXB4IDFweCk7IHBhZGRpbmc6IDBweDsgYm9yZGVy OiAwcHg7IGhlaWdodDogMXB4OyB3aWR0aDogMXB4OyBvdmVyZmxvdzogaGlkZGVuOyB6LWluZGV4 OiAtMTAwMDsiPjwvZGl2PgoJCQk8ZGl2IGlkPSJBY2NEQzEzOTg3MjY5NjM4MjgiPgoJCQkJPHVs IGFyaWEtb3ducz0ibm9kZTItMSBub2RlMi0yIiByb2xlPSJncm91cCIgaWQ9ImFyaWExMzk4NzI2 OTYzODI2Ij4KCQkJCQk8bGk+CgkJCQkJCTxhIGhyZWY9IiMiIGlkPSJub2RlMi0xIiBjbGFzcz0i bGVhZiBhY3RpdmUiIGFyaWEtbGFiZWw9IlNDRU5FIEkuIiByb2xlPSJ0cmVlaXRlbSIgYXJpYS1z ZXRzaXplPSIyIiBhcmlhLXBvc2luc2V0PSIxIiBhcmlhLWxldmVsPSIyIiB0YWJpbmRleD0iLTEi IGFyaWEtc2VsZWN0ZWQ9ImZhbHNlIj4KCQkJCQkJCTxzcGFuPlNDRU5FIEkuPC9zcGFuPgoJCQkJ CQk8L2E+CgkJCQkJPC9saT4KCQkJCQk8bGk+CgkJCQkJCTxhIGhyZWY9IiMiIGlkPSJub2RlMi0y IiBjbGFzcz0ibGVhZiIgYXJpYS1sYWJlbD0iU0NFTkUgSUkuIiByb2xlPSJ0cmVlaXRlbSIgYXJp YS1zZXRzaXplPSIyIiBhcmlhLXBvc2luc2V0PSIyIiBhcmlhLWxldmVsPSIyIiB0YWJpbmRleD0i LTEiIGFyaWEtc2VsZWN0ZWQ9ImZhbHNlIj4KCQkJCQkJCTxzcGFuPlNDRU5FIElJLjwvc3Bhbj4K CQkJCQkJPC9hPgoJCQkJCTwvbGk+CgkJCQk8L3VsPgoJCQk8L2Rpdj4KCQkJPGRpdiBzdHlsZT0i cG9zaXRpb246IGFic29sdXRlOyBjbGlwOiByZWN0KDFweCAxcHggMXB4IDFweCk7IHBhZGRpbmc6 IDBweDsgYm9yZGVyOiAwcHg7IGhlaWdodDogMXB4OyB3aWR0aDogMXB4OyBvdmVyZmxvdzogaGlk ZGVuOyB6LWluZGV4OiAtMTAwMDsiPgoJCQk8L2Rpdj4KCQk8L2Rpdj4KCTwvbGk+Cgk8bGk+CgkJ PGEgaHJlZj0iIyIgaWQ9Im5vZGUzIiBjbGFzcz0iYnJhbmNoIiBhcmlhLWxhYmVsPSJBQ1QgSUlJ IiByb2xlPSJ0cmVlaXRlbSIgYXJpYS1zZXRzaXplPSI0IiBhcmlhLXBvc2luc2V0PSIzIiBhcmlh LWxldmVsPSIxIiB0YWJpbmRleD0iLTEiIGFyaWEtc2VsZWN0ZWQ9ImZhbHNlIiBhcmlhLWV4cGFu ZGVkPSJmYWxzZSI+CgkJCTxzcGFuPkFDVCBJSUk8L3NwYW4+CgkJPC9hPgoJPC9saT4KCTxsaT4K CQk8YSBocmVmPSIjIiBpZD0ibm9kZTQiIGNsYXNzPSJicmFuY2giIGFyaWEtbGFiZWw9IkFDVCBJ ViIgcm9sZT0idHJlZWl0ZW0iIGFyaWEtc2V0c2l6ZT0iNCIgYXJpYS1wb3NpbnNldD0iNCIgYXJp YS1sZXZlbD0iMSIgdGFiaW5kZXg9Ii0xIiBhcmlhLXNlbGVjdGVkPSJmYWxzZSIgYXJpYS1leHBh bmRlZD0iZmFsc2UiPgoJCQk8c3Bhbj5BQ1QgSVY8L3NwYW4+CgkJPC9hPgoJPC9saT4KPC91bD4K CjxwPmNvbnRlbnQgYWZ0ZXI8L3A+
