Bug 2004918 - Remove nsHttpConnection::RequestDone to prevent premature H2 tunnel close, r=necko-reviewers,valentin
Previously we set mRequestDone = true right after writing the HTTP request. That state propagated to Http2StreamTunnel::mSendClosed, and in Http2StreamBase::ReadSegments the stream was got closed.
As a result, an HTTP/2 tunnel could be closed immediately after sending the request bytes, failing to receive the response.
