url.set() doesn't work as expected with property 'origin'

[egold]

Very simple test:

const url = new Url("http://www.example.com/foo/bar");
url.set('origin', 'https://anotherorigin.com')
console.log('URL origin:', url.origin);
//Expected value: https://anotherorigin.com
//Actual value: http://www.example.com

Does not behave as described in documentation. Unless origin is an exception case for some reason, in which case it should be documented.

I get that it would be, since origin is a combination of other properties, but some warning/exception against using .set('origin') (OK) or support for being able to set it (better) would be great.

FWIW same thing happens using parse() code path:

var parsed = parse('http://www.example.com/foo/bar')
parsed.set('origin', 'https://anotherorigin.com')
console.log('Parsed:', parsed)
//Expected value: https://anotherorigin.com
//Actual value: http://www.example.com

I'd like to know when it'll be fixed
