      3 This test case is used to prove HTMLParserScheduler should be suspended when page loading is deferred. See https://bugs.webkit.org/show_bug.cgi?id=48077.
      4 However, this test case can work only when customHTMLTokenizerChunkSize() is equal to or smaller than 256. To reproduce the problem with other settings, try
      5 adding more tags into body.
      6 
      7 To use the test case, open it in browser, when the alert shows up, wait for a few seconds, and close the alert. If it shows "Error detected", that means the problem exists.
