http2 server closing stream exception

[TobyEalden]

Version: deno 2.0.0 (stable, release, aarch64-apple-darwin)

As part of investigation into #24845, I wrote a test that exposed another (seemingly unrelated) issue.

If an http2 server closes the stream while a client is connected an exception is thrown:

error: Uncaught (in promise) Http: error reading a body from connection: stream closed because of a broken pipe
    at async Object.pull (ext:deno_web/06_streams.js:938:27)

To reproduce the issue see https://github.com/TobyEalden/deno-http2-stream-test

I can't see a way to easily catch or avoid this error other than using a setTImout as shown here, and in any case the same code running under nodejs works as expected.

Hi, I don't know if this is related but I'm facing a similar issue with this error output, maybe can help in the tracing of the error:
