 /**
  * A configuration for running layout tests with testrunner.
  * This configuration is similar to the interactive_html_config
  * as it runs each test in its own IFrame. However, where the former
  * recreated the IFrame for each test, here the IFrames are preserved.
  * Furthermore we post a message on completion.
