Applying defaults with a base URL

https://github.com/kenchris/urlpattern-polyfill/blob/3b7dde94e60b9353bd54328c8b61078175a2c816/src/url-pattern.ts#L68-L73

I’m not sure if i misunderstood or this is a bug/awkwardness, but essentially:

(new URLPattern({pathname: '/foo'})).pattern;
// produces:
{
  "hash": "*",
  "hostname": "*",
  "password": "*",
  "pathname": "/foo",
  "port": "*",
  "protocol": "*",
  "search": "*",
  "username": "*"
}

(new URLPattern({pathname: '/foo', baseURL})).pattern;
// produces:
{
  "hash": "",
  "hostname": "",
  "password": "",
  "pathname": "/foo",
  "port": "",
  "protocol": "",
  "search": "",
  "username": ""
}

this means the computed regex patterns become ^$ in the latter, rather than ^(.*)$.

so we can’t rely on defaults if we have a base URL? the comment i quoted seems to hint at the fact that its on purpose, but it feels like the behaviour should be the same to me

By the way, this discussion might be better as a https://github.com/WICG/urlpattern spec issue.

@kenchris I think this can probably be closed unless you want to update some documentation within this repo.
