<pre>testRunner.setPageVisibility is somewhat broken in WebKitTestRunner, creating an opportunity for races. It is asynchronous, and there are tests that just call the function and terminate without waiting for a visibility change event, thus leaving the following test to handle the message in UI process.
But once again, there is no indication that this is somehow breaking this particular test - in a failing run on the bot, no preceding tests call setPageVisibility.</pre>
