Parent container with percentage for padding not working in IE11

I have a parent container that has no width, but 10% padding. Works fine in most browsers with exception of IE11. Anyway, I’ve narrowed it down to and fixed it with the following. Sorry I would do a pull request/submit a change, but haven’t done it before. Cheers.

helpers.getMaximumWidth = function(domNode) {
		var container = domNode.parentNode;
		var paddingLeft = helpers.getStyle(container, 'padding-left');
		var paddingRight = helpers.getStyle(container, 'padding-right');

		if (paddingLeft.indexOf('%') > -1)
		    paddingLeft = container.clientWidth / parseInt(paddingLeft, 10);
		else
		    paddingLeft = parseInt(paddingLeft, 10);

		if (paddingRight.indexOf('%') > -1)
		    paddingRight = container.clientWidth / parseInt(paddingRight, 10);
		else
		    paddingRight = parseInt(paddingRight, 10);
		
		var w = container.clientWidth - paddingLeft - paddingRight;
		var cw = helpers.getConstraintWidth(domNode);
		return isNaN(cw)? w : Math.min(w, cw);
	};

@andi-b this would make a good PR. I found some good docs on how to make a PR if you’re interested

@benmccann I looked at this just now as well. Not sure why this fix changes anything, as the math should work out identically. I tested again in IE11 using the latest code from master. I set the padding on the canvas container to '10%'. The chart was identical in IE11 and FireFox so I’m calling this resolved
