WebSocket URL property undefined

[tegandbiscuits]

The properties url, protocol, and bufferedAmount on instances of WebSocket are returning undefined (on iOS at least).

I'm able to successfully connect using both of the given values, but accessing either doesn't work as expected. This causes problems for clients that depend on having either value.

However, readyState seems to be working correctly. I haven't checked extensions.

React Native version:

Steps To Reproduce

1. Create a new WebSocket that uses a subprotocol
2. After connecting, attempt to access url or protocol

Describe what you expected to happen:

If I do const ws = new WebSocket('ws://localhost:8080, 'some-protocol')`

ws.url and ws.protocol should return ws://localhost:8080 and some-protocol respectively.

Here's a minimal example of a ws server and clients. The browser client works as expected, but the react native app does not.
