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
