Version

master for R8.

Describe the bug

Some features are not implemented in IE11, need to bring in a polyfill or use legacy way to do stuff.

  • Set is not a full implementation, missing Symbol.iterator
    • Use core-js to polyfill Set
  • CustomEvent.constructor is missing
    • Use document.createEvent and Event.initEvent instead

Steps to reproduce

Host Web Chat on IE11.

Expected behavior

Basic operations are working.
