If aria-labelledby is added with a reference to an element the aside's role is AXGroup. This causes it to show up in the Web Rotor as “text in referenced element” + “complementary”.

This is expected behavior for anything with presentation 266353 2015-12-01 05:32:04 -0800 2015-12-01 05:32:04 -0800 Code example aside.html text/html 369 webkit PCFET0NUWVBFIGh0bWw+CjxodG1sIGxhbmc9ImVuIj4KPGhlYWQ+CiAgPG1ldGEgY2hhcnNldD0i VVRGLTgiPgogIDx0aXRsZT5Bc2lkZSB3aXRoIHByZXNlbnRhdGlvbiByb2xlIGFuZCBsYWJlbGxl ZGJ5PC90aXRsZT4KICA8c3R5bGU+CiAgICBhc2lkZSB7CiAgICAgIHBhZGRpbmc6IDVweDsKICAg ICAgZm9udC1mYW1pbHk6IHNhbnMtc2VyaWY7CiAgICAgIGJhY2tncm91bmQ6ICNlZmVmZWY7CiAg ICB9CiAgPC9zdHlsZT4KPC9oZWFkPgo8Ym9keT4KICA8YXNpZGUgYXJpYS1sYWJlbGxlZGJ5PSJs YWJlbCIgcm9sZT0icHJlc2VudGF0aW9uIj4KICAgIDxoMiBpZD0ibGFiZWwiPkFzaWRlPC9oMj4K ICA8L2FzaWRlPgo8L2JvZHk+CjwvaHRtbD4K
