SCRIPT16386 jQuery.contains in ie9 with quirks mode

Question

I am using an external library called "deps.js". I forked it on github and modified it a little bit. You can find it here:

https://github.com/ckosmowski/jquery-interdependencies/blob/master/deps.js

Unfortunately i'm stuck to the quirks mode of ie9. i'm getting the following error:

SCRIPT16386 Schnittstelle nicht unterstützt

(Which can be translated to "interface not supported")

The error message is refering to:

jquery-1.7.js, Line 5244 Character 3 which is:

if ( document.documentElement.contains ) {
Sizzle.contains = function( a, b ) {
    return a !== b && (a.contains ? a.contains(b) : true); //This is the line from the error message
};

In Standards mode this does not appear.

Answer 1

I don't think that this solves the main problem but the symptoms mentioned in the question seem to be solved with newer jQuery versions. I just changed the jQuery version from 1.7 to 1.10.2 and now it works perfectly in quirks mode.
