IE10 can't run the demo because you use ES6 features (const, looks like) that it doesn't have.
The doctype detection also seems to drop it into quirks mode. You could probably fix that by using a standards doctype, but you could also just put in the meta tag that forces IE to run in standards mode for quirks documents.
