instanceof errors in IE 11

mapbox-gl-js version: 0.45.0
browser: IE 11

Official examples:

• https://www.mapbox.com/mapbox-gl-js/example/animate-images/
• https://www.mapbox.com/mapbox-gl-js/example/cluster/

The examples work, but throw an error in IE 11 for web_worker_transfer.js.

Invalid operand to 'instanceof': Function expected

export function deserialize(input: Serialized): mixed {
    if (input === null ||
        input === undefined ||
        typeof input === 'boolean' ||
        typeof input === 'number' ||
        typeof input === 'string' ||
        input instanceof Boolean ||
        input instanceof Number ||
        input instanceof String ||
        input instanceof Date ||
        input instanceof RegExp ||
        input instanceof ArrayBuffer ||
        ArrayBuffer.isView(input) ||
        input instanceof ImageData) {
        return input;
    }

Does IE 11 require a core-js polyfill to work correctly?

I think it's because ArrayBuffer is not fully supported in IE.

Closing because IE 11 is no longer supported. Thanks for reporting this.
