Twenty Sixteen compat file loaded in the dashboard.

[bhubbard]

I have jetpack loaded on a fresh wordpress install using development mode. I ran the audit tool and noticed that a file called twentysixteen.css.

Currently this file loads in the WordPress admin, but I can't find any page admin page where it is used.

I also noticed it is loading a non-minified file:

jetpack/modules/theme-tools/compat/twentysixteen.php

Lines 15 to 28 in a15e502

	function twentysixteen_init_jetpack() {
	/**
	* Add our compat CSS file for custom widget stylings and such.
	* Set the version equal to filemtime for development builds, and the JETPACK__VERSION for production
	* or skip it entirely for wpcom.
	*/
	$version = false;
	if ( method_exists( 'Jetpack', 'is_development_version' ) ) {
	$version = Jetpack::is_development_version() ? filemtime( plugin_dir_path( __FILE__ ) . 'twentysixteen.css' ) : JETPACK__VERSION;
	}
	wp_enqueue_style( 'twentysixteen-jetpack', plugins_url( 'twentysixteen.css', __FILE__ ), array(), $version );
	wp_style_add_data( 'twentysixteen-jetpack', 'rtl', 'replace' );
	}
	add_action( 'init', 'twentysixteen_init_jetpack' );

I suggest we load a minified version, and not in the WordPress Admin. Looks like the same might happen with the twentyfifteen.css file.
