Jetpack comment iframe height calculation problem

Hi,

I’m experiencing problems with a calculation of a height of a jetpack comment iframe (id=”jetpack_remote_comment”).

Console shows an issues with an origin:

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

I’ve found an issue in execution of:

parent.postMessage( height, parentOrigin );

In this method:

HighlanderComments._JetpackResizeCallback = function() {
   var currentHeight = heightContainer.outerHeight();

   if ( currentHeight == height ) {
      return;
   }

   height = currentHeight;

   parent.postMessage( height, parentOrigin );
};

This issue has arisen after our partner (http://dennikn.sk) joined our project and we changed the domain of the site from http://varme.sk to a sub-domain http://varme.dennikn.sk . Everything seems to be working properly except this height issue.

You can spot this behavior e.g. here:

Do you have any idea, how to fix this?

Thank you
Varme
