Regression from 13.6.2 to 13.7.0: clicking a checkbox no longer fires a change event

[cyyynthia]

Describe the bug
When triggering a click event on an HTMLInputElement, the change event is no longer fired in version 13.7.0 and up. Seems to affect all versions up to latest.

To Reproduce
Steps to reproduce the behavior:

1. Get an HTMLInputElement with an event listener attached to the change event
2. Trigger a click (using .dispatchEvent(new MouseEvent('click'))
3. Observe that the event listener hasn't been fired

Expected behavior
The click and change events should both be fired.

Device:

• OS: Windows, Linux
• Browser: Node
• Version: 13.7.0 and up

After a bit more testing; it seems the tooling I'm using does dispatch a new MouseEvent('click'), which does not extend PointerEvent causing the instanceof checks to fail. Hope this helps!
