Lets not add more of these script tests, can you just put the script inside the
html file?

+var heightBeforeLayout = iframe.contentWindow.innerHeight;
+var forceLayout = iframe.offsetHeight;
+var heightAfterLayout = iframe.contentWindow.innerHeight;
+
+shouldBe('heightBeforeLayout', 'heightAfterLayout');
