The base URI is used when expanding relative links.  So if you have HTML
that looks like

<a href="foo.html"><img src="img.png"></a>

then the browser can't resolve those two URLs without having the base
URI.  So you'd pass in a base URI of https://example.com/foo/bar/zot if
that's where the HTML snippet is from.

When the URLs are absolute, the base URI is irrelevant.
