 '''Current behavior'''

 When the skins are upgraded then the communication to the parent node
 using postMessage is blocked when the user is on the URL that has
 specified port. Example: ''example.com:81''.

 I see in console:

   Failed to execute 'postMessage' on 'DOMWindow': The target origin
 provided ('http://localhost') does not match the recipient window's origin
 ('http://localhost:81').

 '''Expected behavior'''

 File ''wp-admin\includes\class-wp-upgrader-skins.php'' line 168 contains:

 {{{
 window.parent.postMessage( JSON.stringify( { action:
 "decrementUpdateCount", upgradeType: "' . $type . '" } ),
 window.location.protocol + "//" + window.location.hostname );
 }}}

 The '''targetOrigin''' for the ''postMessage'' should also contains port
 number. E.g. ''window.location.hostname + window.location.port''
