prerender: The `url` is triming the fragment under prerender

Bug Report

Current Behavior

When saving a URL that includes a fragment identifier, the meta API url response field strips out any fragment identifier that was in the original URL

In: https://example.com/#hello
Out: https://example.com/

Expected behavior/code

I expect the url field to show what's in the browser address bar after the page loads. If following the link in my browser preserves the fragment, so should Microlink.

Additional context/Screenshots

This is a problem for my use case: I use the url field to get a canonical link to show users, since it resolves HTTPS redirects, shortlinks, etc.

I can't do that if the url field strips out important data (text highlights, or which part of the page is being linked to).

Start by reproducing the prerender behavior with a URL such as https://example.com/#hello, then trace how the meta API derives its url response from the loaded page. Done means the response preserves the original fragment identifier after redirects and prerendering.
