In JS, EventTarget.prototype is undefined.  It should be defined and contain
addEventListener and company, e.g. EventTarget.prototype.addEventListener.

Oddly enough, EventTarget itself is defined, but contains no visible properties.

Workaround is to access/set addEventListener and company on Element.prototype,
Window.prototype, and HTMLDocument.prototype.

Reproducible: Always

Sounds like EventTarget should be in some prototype chains here...
