a note: this pass condition isn't the expected behavior.  in fact, it sort of
feels like a bug in the feature that this passes in most scenarios.

the expected behavior is that the instant tab is not being shown to the users. 
oddly, by the info, it appears that on most platforms it is actually loading and
rendering like normal, but there is some other logic causing it to not be
displayed.  huyen is looking into this, because it is the same expected behavior
for another test case he picked up.

+        self.assertTrue(self.GetInstantInfo()['showing'],
+                        'User can preview porn words without enter key')
