WebSocket object with an open connection must not be garbage collected if there are any event listeners registered for message events.

Shouldn't it also not be garbage collected if there are listeners for open, error and close? What about when the connection is not yet established?

I think the policy should be:

if readyState is CONNECTING:
  has 'open' event listener: don't collect
  has 'message' event listener: don't collect
  has 'error' event listener: don't collect
  has 'close' event listener: don't collect

if readyState is OPEN:
  has 'open' event listener: OK to collect
  has 'message' event listener: don't collect
  has 'error' event listener: don't collect
  has 'close' event listener: don't collect

if readyState is CLOSING:
  has 'open' event listener: OK to collect
  has 'message' event listener: OK to collect
  has 'error' event listener: OK to collect
  has 'close' event listener: don't collect

if readyState is CLOSED:
  has 'open' event listener: OK to collect
  has 'message' event listener: OK to collect
  has 'error' event listener: OK to collect
  has 'close' event listener: OK to collect
