 * This sjs file supports three endpoint:
 * - "sjs_imported_stylesheet_edit.sjs" -> will return a text/css content which
 *   will be either INITIAL_CONTENT or UPDATED_CONTENT. Initially will return
 *   INITIAL_CONTENT.
 * - "sjs_imported_stylesheet_edit.sjs?update-stylesheet" -> will update an
 *   internal flag. After calling this URL, the regular endpoint will return
 *   UPDATED_CONTENT instead of INITIAL_CONTENT
 * - "sjs_imported_stylesheet_edit.sjs?setup" -> set the internal flag to its
 *   default value. Should be called at the beginning of every test to avoid
 *   side effects.
