karthik-phl opened PR #12904 from karthik-phl:fix_issue_12903 to bytecodealliance:main:

• Fixes #12903 and tests to validate
• This fix is necessary because zero-length data frames are valid per the http_body::Body trait contract (which does not forbid them) and RFC 9113 §6.1 (which explicitly permits zero-length DATA frames), so HostBodyStreamProducer must tolerate them as a consumer of poll_frame. Similarly, a zero-capacity destination is a valid call condition. In both cases, returning StreamResult::Completed without producing any items violates the contract enforced in futures_and_streams.rs:2536–2544 and causes an immediate trap.
