Bug 117706 – AX: display: -webkit-box formatted <li> elements are not assigned correct accessibility roles

• Status: RESOLVED
• Resolution: FIXED
• Component: Accessibility

[Brent Fulgham]

The logic that determines accessibility roles for different HTML tokens does the wrong thing for <li> elements that have been given the "-webkit-box" display style.

List items should be assigned the "ListItemRole" Web Role, but are instead given a "GroupingRole".

looking good. i would suggest updating the layout test to make it more specific.

I try to avoid the attributesofChildren() method these days because it's not very specific if something breaks.

For this test I would probably do

var listItem = document.accessibleElementById("test 1");
shouldBe("listeItem.role", "'AXRole: AX...'");

I looked at using this, but I'd have to have a custom test for mac and one for windows, since it would be:

Mac:
shouldBe("listItem.role", "'AXRole: AX...'"); 

Win:
shouldBe("listItem.role", "'list item'");

and so forth.

But I'll definitely change the "attributesOfChildren()" call to "accessibleElementById()".

I've also done

debug("List item role: " + listItem.role)

so that you can just use different expectations
