clone() of LINK from parent followed by append() into child document fails on IE6 and IE7

Reported by: Owned by:

Blocked by: Blocking:

A page (the parent) contains an <iframe> (the child). The child <iframe> uses jQuery to find relevant <script>'s and stylesheet <link>'s sourced in the <head> of the parent, and attempts to add those resources to the <head> of itself. In other words, <script>'s and <link>'s found in the parent are dynamically added to the child using jQuery.

This works in IE8+, FF3+, Chrome and Safari -- in these cases, I see that the <script>'s and CSS related <link>'s are correctly found, cloned and appended to the <head> of the child <iframe>. In IE6 and IE7, the same code fails to properly clone() and append() any associated <link>'s from the parent into the child. Note that <script>'s work fine, but IE6 and IE7 reports an "illegal argument" error inside of jQuery when cloning and appending a <link>.

I tried to reproduce this bug in JSFiddle, but couldn't fit things together correctly in that environment. As a result, my write-up of the problem, and code that reproduces the issue, can be found at:

A quick search of existing bugs produced no interesting results.

Please let me know if you need more information.

Unfortunately we can't work around this browser issue inside core. You can Google around and see this has been a problem in IE6/7 for a decade, e.g.

You might try using an HTML rendering instead.
