It seems like $redirect defined by parameter $redirect on line 4445 can also be of type string; however, Jetpack::build_authorize_url() does only seem to accept boolean, maybe add an additional type check?

This check looks at variables that have been passed in as parameters and are passed out again to other methods.

If the outgoing method call has stricter type requirements than the method itself, an issue is raised.

An additional type check may prevent trouble.

	 * This methods removes all of the registered css files on the front end
6274
	 * from Jetpack in favor of using a single file. In effect "imploding"
6275
	 * all the files into one file.
6276
	 *
6277
	 * Pros:
6278
	 * - Uses only ONE css asset connection instead of 15
6279
	 * - Saves a minimum of 56k
6280
	 * - Reduces server load
6281
	 * - Reduces time to first painted byte
6282
	 *
6283
	 * Cons:
6284
	 * - Loads css for ALL modules. However all selectors are prefixed so it
6285
	 *		should not cause any issues with themes.
6286
	 * - Plugins/themes dequeuing styles no longer do anything. See
6287
	 *		jetpack_implode_frontend_css filter for a workaround
6288
	 *
6289
	 * For some situations developers may wish to disable css imploding and
6290
	 * instead operate in legacy mode where each file loads seperately and
6291
	 * can be edited individually or dequeued. This can be accomplished with
6292
	 * the following line:
6293

6294
