Access-Control-Allow-Origin in AssetController

Lines 1234 to 1235 in 4dff99b

	'Content-Type' => $thumbnail->getMimeType(),
	'Access-Control-Allow-Origin', '*',

Is the above , '*' intentional? Shouldn't it be => '*'?

Have you been able to research if this code is as intended @fashxp?

By looking at
