Thanks, this looks reasonable to me modulo nits. This means that service workers do not get to see the header ever unless it was set by a web developer. Do we have test coverage for that as well?

Priority
request header #1718(See WHATWG Working Mode: Changes for more details.)

Priority
HTTP header from HTTP Extensible Priorities (RFC 9218).The actual priority values are implementation-specific but this change makes it clear that an existing value should not be overwritten if the header is already present.
Fix #1718
