I don't have a strong opinion on title vs description; I think it's more important that WebCore presents something consistent; the Mac port can choose to map those to the NSAccessibility APIs however it wants.

Here's a simpler example: take this button:

  <button>Alpha</button>

Right now WebKit returns "Alpha" as either the title or the description - I don't recall which one - but it's not both.

Now, either of these two buttons should return "Beta" in place of whatever previously returned "Alpha":

  <button aria-label="Beta">Alpha</button>
  <button aria-labelledby="beta">Alpha</button>
  <span id="beta">Beta</span>

The ARIA spec is pretty clear that this is what should happen. Be sure to think of this in layers; WebCore should implement something that's consistent with the ARIA spec, and each WebKit port then matches this up with the appropriate platform APIs - i.e. there's no reason each platform must have a concept of "title" and "description" that agree.

For suppressing the test, look at files like LayoutTests/platform/win/Skipped - you'll need to add this test to each Skipped file for platforms that are unable to run this test. Currently that's every platform other than Mac.
