If aria-describedby is set on an ARIA dialog, Mozilla will expose this as the description. We should use this in preference to our own getDialogText code.
Test cases: tests 2 and 3 at http://www.accessibleculture.org/testing/aria/alertdialog/

Actually, probably a bug; we really should use information that is given to us for free. :)

Implemented in 3056065.
We were unable to find any dialogs that expose a pointless description. If some are found, we will need to special case them or reconsider this fix.

It seems this issue is still occurring or occurring again in Firefox 3.7. For the provided test cases the dialog descriptions are no longer announced by NVDA, even though they are exposed in MSAA

Broken support in Firefox 3.7 is known and is because of MozillaBug:539252. See also MozillaBug:561924. Unfortunately, I suspect that NVDA will break with some version of Firefox no matter what we do.

Fixed in 60c9860 without breaking Firefox 3.6. Yay!
