http(s) scheme for WebSocket gives an error anyway

What specific section or headline is this issue about?

Examples

What information was incorrect, unhelpful, or incomplete?

at least the WebSocket("https://not-example.com/") example is totally useless as the https scheme will raise an exception in the WebSocket interface, independently from the CSP mechanism, so not-example.com will not even be looked at

What did you expect to see?

I expected to understand how can I not specify the WebSocket protocol for ws://example.com/ in the connect-src and still be able to connect using WebSocket.

Do you have any supporting links, references, or citations?

Do you have anything more you want to share?

Fixed by #25220. But see also #26731; soon enough, if not now, http will be allowed in WebSocket.
