+    It's unclear what the pass condition should be for this test.
+    Implementations:
+    Firefox, Opera (Presto): terminate request with no further events when IFRAME is removed.
+    Chrome: completes request to readyState=4 but responseText is "" so it's pretty much terminated with an extra event for "DONE" state
+    Pass condition is now according to my suggested spec text in https://github.com/whatwg/xhr/pull/3 , if that's not accepted we'll have to amend this test
