  //    https://github.com/web-platform-tests/wpt/blob/master/tools/wptrunner/wptrunner/executors/reftest-wait_webdriver.js

  //    comparison is delayed until that class attribute is removed. To support
  //    this feature, we use a mutation observer.
  //    https://web-platform-tests.org/writing-tests/reftests.html#controlling-when-comparison-occurs

  // the code behind a flag. The flag is safe to be installed on testRunner
