/**
 * Frame script that will be injected into the test browser
 * to cause plugin crashes, and then manipulate the crashed plugin
 * UI. The specific actions and checks that occur in the frame
 * script for the crashed plugin UI are set in the
 * test:crash-plugin message object sent from the parent. The actions
 * and checks that the parent can specify are:
 *
 * pleaseSubmitStyle: the display style that the pleaseSubmit anonymous element
 *                    should have - example "block", "none".
 * submitComment:     the comment that should be put into the crash report
 * urlOptIn:          true if the submitURLOptIn element should be checked.
 * sendCrashMessage:  if true, the frame script will send a
 *                    test:crash-plugin:crashed message when the plugin has
 *                    crashed. This is used for the last test case, and
 *                    causes the frame script to skip any of the crashed
 *                    plugin UI manipulation, since the last test shows
 *                    no crashed plugin UI.
