1. Load the testcase 2. In the JS console, paste Components.classes["@mozilla.org/accessibilityService;1"] .getService(Components.interfaces.nsIAccessibleRetrieval); 3. Focus the testcase(?) ###!!! ASSERTION: should only care when we have an outside bullet: 'mContent->GetPrimaryFrame()->GetStyleDisplay()->mDisplay == NS_STYLE_DISPLAY_LIST_ITEM && HaveOutsideBullet()', file /builds/slave/mozilla-central-linux64-debug/build/layout/generic/nsBlockFrame.cpp, line 6542

I think BulletIsEmptyExternal() should check for HaveOutsideBullet()...

(In reply to comment #2) > I think BulletIsEmptyExternal() should check for HaveOutsideBullet()... What is HaveOutsideBullet for?

Bullets can be inside or outside. See http://www.w3.org/TR/CSS21/generate.html#propdef-list-style-position Does a11y need to create a bullet accessible in both cases?

(In reply to comment #4) > Does a11y need to create a bullet accessible in both cases? I think so.

Then it sounds like we need a way to make BulletIsEmpty() work for inside bullets, right?

Yes. For that matter, BulletIsEmpty seems like it should work too, except for the assert bit.
