[IE] 32-bit windows has broken document.domain for IPv6 address, causing access denied errors

[Damian]

This issue is partly related to #5434. On a 64-bit server, the fix for #5434 works but on a 32-bit server a different error occurs.

The issue is that 32-bit IE does not appear to support IPv6 addresses correctly, especially when getting document.domain. IE truncates the ip address when it reaches the first colon ":" in the address. This causes "access denied" errors when new IFrames are opened by CKEditor.

On (32-bit) IE:

document.domain = "[fe80:"
window.location.hostname = "fe80::fe80:fe80:fe80:fe80" 

A work-around is required for this IE bug.

We have no alternation on domain relaxation detection currently, leave it open for investigation.
