[0.8] SVG elements fail on IE11 due to missing classList #1490

Opening the following test case on IE11 will throw an error in the _transformElement_ function in the _style-transformer.html_ file because the element doesn't have a classList. Chrome shows the SVG element without a problem.

Could we maybe add a check for this in the starting condition, like if(useAttr || !element.classList)?
