This is an asynchronous script test which navigates the main page but relies on js-test-post.js calling LayoutTestController.waitUntilDone(). It's possible for the main page to be navigated and hence the load of js-test-post.js to be cancelled before LayoutTestController.waitUntilDone() is called, which causes the test to fail.
