There seem to be a small handful of cases where we want this--controls that gain focus immediately after a dialog appears, for instance. We allow these edge cases to indicate that the next focus shouldn't stop speech, then clear it on cases where speech isn't stopped. This is a bit hacky, but seems cleaner than anything else I came up with.
