Per spec change https://github.com/w3c/presentation-api/pull/426 we will now remove receiver connections from the PresentationConnectionList when they are closed.
This issue tracks the work to implement and update LayoutTests etc.
I do not expect any web compatiblity issues. Not sure this justifies an intent to implement.
