MessageEvent is not of type Event

[dheardal]

Describe the bug

For a normal event this test runs fine:

fireEvent(window, new Event('message'));

However this:

fireEvent(window, new MessageEvent('message'));

throws:
TypeError: Failed to execute 'dispatchEvent' on 'EventTarget': parameter 1 is not of type 'Event'.

This test worked previously when using jest

Reproduction

• This is when using the jsdom envrionment

For any others having this issue, this is a workaround:
