Featured image not showing when using SVG

[Swellfire]

After enabling SVG

function cc_mime_types( $mimes ){
	$mimes['svg'] = 'image/svg+xml';
	return $mimes;
}

add_filter( 'upload_mimes', 'cc_mime_types' );

and setting a featured image to a SVG, the image does not show up in the backend. Worked in 3.6

I'm curious how this could have worked for 3.6 since it will not get the height/width of an image. And this is something really important. If it did worked in 3.6 then I tend to say it was a bug in 3.6.

Edit: I will look into it and see it I can reproduce this in 3.6

Thanks for the report, Swellfire.
