What is the current behavior?

matchMedia is supposed to return a MediaQueryList which inherits from the EventTarget interface. As such the stub object returned from the mock should have addEventListener, removeEventListener, and dispatchEvent methods. It was also missing the media property.

GitHub Issue Number: N/A

What is the new behavior?

Missing properties were added:

• addEventListener
• removeEventListener
• dispatchEvent
• media

Does this introduce a breaking change?

• [ ] Yes
• [x] No

Testing

I got my unit tests to run for my project that uses matchMedia, also I added tests to ensure the moc-doc matches expectations going forward.

Other information

Tests included, and a typo fix.
