    • Hello,

      Thank you for providing this information about the issue. We’ve removed SharedArrayBuffer support from EdgeHtml for security reasons. However, we’ve added the ‘messageerror’ event to our type system.

      SharedArrayBuffers do not exist, the ‘messagerror’ event does not
      fire. If we add another feature like
      SharedArrayBuffer in the future, the ‘messageerror’ event will fire.

      Best Wishes,

      The MS Edge Team

    • FWIW, ArrayBuffer can also trigger this event, when you fail to allocate it due to OOM in the new process. It’s rather obscure and hard to test for though.
