Deno test WebSocket completing cleanly, but reporting BadResource: Bad resource ID

[aricart]

I am a bit miffed by this error reported by the test runner (notice the async/ops resource sanitizer is not printing (I am the one doing the print). The test completes, reports passed, but a trace at the end.
Any hints, thoughts?

running 1 tests
test clean shutdown ...
{ "0": "stdin", "1": "stdout", "2": "stderr", "3": "webSocketStream" }
ok (11ms)

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out (11ms)
