Jan-Ivar might want to comment here, as he has often explained that Firefox does its parsing based on WebIDL and that an unknown constraint disappears during that process.  As our standard list of constrainable properties becomes more and more supported the need to check in advance for such unknown constraints should also diminish, unless of course the developer is specifically using a non-standard (e.g., experimental) constraint.

But we're still required by contract to call either the success or error callback, and what it sounded like you were saying was that the browser was free to ignore the constraint completely and return success.
