HTTP: cancelling request not working for streaming

[egoist]

Once fetch_read_body is fired, aborting the fetch will stop working

Could you give #2562 a try and see if there is any use cases I missed?

I mainly tested the following case:

const abort = new AbortController();
const res = await fetch("someurl", { signal: abort.signal })
const reader = res.body.getReader();

reader.read() // ensure we got some data
abort.abort() // abort the requst
reader.read() // fails as the stream is closed
