1793710 - [CTW] Support MSAA string role hack

Status: RESOLVED FIXED

(Core :: Disability Access APIs, task)

Description

[James Teh [:Jamie]]

Gecko has a hack where it exposes strings for unmapped MSAA roles. We want to remove this hack; see bug 798492. However, that involves figuring out 44 mappings, which is not something I want to spend time on right now.

For RemoteAccessible, we just return E_FAIL in this case. That's not ideal and might confuse a client or at least make someone think something is broken when it isn't. Instead, we should return a string as best we can.

I originally wrote this patch to see if it fixed live regions with JAWS (bug 1786240). Sadly, it doesn't, but since I've written the patch, I may as well submit it.
