postMessage doesn't work in recent IE 11 browsers

[iqjumps]

Hi, I have some problems in my project.

• 
  parent window : a.a.com
  
• 
  popup window: b.a.com
  

When I execute window.opener.postMessage(~~, *) in popup window, parent window can receive event depending on IE versions. (works in all Chrome versions)

version: 11.1.18362.0 / update version: 11.0.110 - works

version: 11.557.17763.0 / update version: 11.0.130 - works

version: 11.1158.17763.0 / update version: 11.0.185 - works

version: 11.1304.17134.0 / update version: 11.0.175 - doesnt work

version: 11.1425.17134.0 / update version: 11.0.185 - doesnt work

version: 11.1868.16299.0 / update version: 11.0.190 - doesnt work

I cant find any issues about it. Are there some changes associated with postMessage or CORS policy?

Thanks.
