• Responding to a current read request through a pull request from a released reader

Could you please backport this to v16.x? The test/wpt/status/streams.json file is complaining about this in the v16.x release branch.

[daeyeon]

Sure. I plan to open a PR that contains all commits related to test/wpt/status/streams.json.
