JointJS doesn't work with newer jQuery Versions (>1.11.1 | > 2.1.1) under Internet Explorer 11

When using JointJS with jQuery Version higher than 1.11.1 or 2.1.1 JointJS doesn’t work under Internet Explorer 11 (I have not tested any other version).

I receive following error message when constructing the Paper:

SCRIPT438: Object doesn't support property or method getElementsByClassName
File: jquery-2.1.3.js, Row: 800, Column: 5

It looks like jQuery can’t search by className (like find(‘.rotatable’)) on SVG DOM elements.

Chrome and Firefox don’t have this problem.

I suggest to use jQuery v2.2.1 if possible. If this is not an option a polyfill is needed. e.g.

if (SVGElement.prototype.contains === undefined) {
    SVGElement.prototype.contains = function(el) {
        return $.contains(this, el);
    };
}

if (SVGElement.prototype.getElementsByClassName === undefined) {
    SVGElement.prototype.getElementsByClassName = function(className) {
        return this.querySelectorAll('.' + className);
    };
}

@kumilingus jQuery 3.0 did not resolve this issue for me, but your polyfill above did. Thank you!
