IE11 - classlist.add error #2

Firstly, this is wonderful work. You are exceptional.

I'm just wondering whether you are aware that an error occurs in IE11 when you click on a pin, the target map__space doesn't get targeted and map__space--selected is not added.

Error SCRIPT5007: Unable to get property 'add' of undefined or null reference

At first I thought the issue had to do with classlist being incompatible with IE11, but that is not the case . It is compatible for ie10+. But I think the issue has to do with IE11 having issue targeting svg, and where classie.js is failing.

Before I dig deeper, I was hoping for any insight that you may have. Beyond this - I am confident of making this work for IE10 and IE11.

Thank you.
