 /**
  * The AdInjectorTest infrastructure. Basically, this allows the test to follow
  * a simple iteration cycle:
  * - Signal the C++ test that we're going to do page setup, and we shouldn't
  *   record any ad-injector events (as some of the page setup could qualify).
  * - Do the page setup, which involves creating a 'playground' for ad injectors
- *   of iframes, embeds, etc. See also ad_injectors.html. We do this set up for
- *   each test, so that none of the tests conflicts with each other.
+ *   of iframes, etc. See also ad_injectors.html. We do this set up for each
+ *   test, so that none of the tests conflicts with each other.
  * - Signal that we are done with page setup, and should start recording events.
  * - Run the next test.
  * - Signal that the test is done, and we should check for the result.
  *
  * This cycle repeats, and should be done synchronously so that we don't end up
  * recording events which we shouldn't, and can attribute each event to its
  * cause.
