node:https: 'tls config unavailable; refusing to listen' under async-dispose (test-https-server-async-dispose)

[proggeramlug]

Summary

test-https-server-async-dispose fails with:

[node:https] tls config unavailable; refusing to listen

An https server created in a context exercised by await using / Symbol.asyncDispose can't resolve its TLS config at listen() time, so it refuses to listen. Either the key/cert options aren't threaded through the async-dispose-wrapped server construction, or the TLS config is torn down too early. Confirm the server gets its TLS config when created under async-dispose.

Acceptance

test-https-server-async-dispose listens and disposes cleanly.
