Steps to reproduce the problem:
I came across the following code in background_fetch_delegate_proxy.cc:

    // Append the Origin header for requests whose CORS flag is set, or whose
    // request method is not GET or HEAD. See section 3.1 of the standard:
    // https://fetch.spec.whatwg.org/#origin-header
    if (fetch_request.mode == network::mojom::FetchRequestMode::kCORS ||
        fetch_request.mode ==
            network::mojom::FetchRequestMode::kCORSWithForcedPreflight ||
        (fetch_request.method != "GET" && fetch_request.method != "POST")) {
      headers.SetHeader("Origin", origin.Serialize());
    }

The comment and spec says to check for GET or HEAD. The code checks for GET or POST. The code is inconsistent with the comment.

What is the expected behavior?
I would expect the second check for method to compare against "HEAD", not "POST".

What went wrong?
This is something I noticed in the source code, not some behavior of the browser that I could reproduce.

Did this work before? N/A
