It looks like when trying to use this component in IE11 it throws errors for "SCRIPT438: Object doesn't support property or method 'assign' " which tracking down the issue means that it doesn't like Object.assign()
I found a workaround if you want to try it (if you really want to support IE11) to use the object-assign package here: https://github.com/sindresorhus/object-assign instead of the native Object.assign()
