What steps will reproduce the bug?

let u = new URL('http://example.net:8080/path')
u.port = 'randomstring'

How often does it reproduce? Is there a required condition?

always

What is the expected behavior?

{
    "href": "http://example.net:8080/path",
    "host": "example.net:8080",
    "hostname": "example.net",
    "port": "8080"
}

What do you see instead?

{
  href: 'http://example.net/path',
  host: 'example.net',
  hostname: 'example.net',
  port: ''
}
