http://www.w3c-test.org/websockets/interfaces/WebSocket/readyState/003.html looks wrong to me: the value it should get is in fact undefined, since the property got deleted from the prototype.

This issue has been open for 3 years :)

Current results:
https://wpt.fyi/websockets/interfaces/WebSocket/readyState/003.html
https://wpt.fyi/websockets/interfaces/WebSocket/readyState/003.html?wss

I get the same error with wpt run locally, but not at http://w3c-test.org/websockets/interfaces/WebSocket/readyState/003.html...

In Chrome devtools I see "Failed to load resource: the server responded with a status of 500 (Internal Server Error)" so something pretty odd is happening here.

Will file a separate issue for that, when fixed perhaps this issue can be reproduced again.
