TEST-UNEXPECTED-PASS | http://mochi.test:8888/tests/toolkit/content/tests/widgets/test_mousecapture_area.html | assertion count 0 is less than expected 1 assertions

Now it fails due to the test expect an assertion being reported, but it seems the assertion doesn't being reported properly when cross-origin enabled,
