Could we perhaps add a very basic layout test to verify that these in fact
reject? Could be as simple as:

navigator.geolocation.registerRegion(new CircularRegion(0, 0)).then(
    function() { testFailed("Promise unexpectedly resolved."); },
    function() { testPassed("Promise rejected as expected."); });

Done (although it seems a bit silly to write tests that we know will break once
the code is actually correct).
