[Bug]: Query string before the hash is not read using useSearchParams

[TomGB]

What version of React Router are you using?

react-router-dom@6.3.0

Steps to Reproduce

const [searchParams, setSearchParams] = useSearchParams();
console.log(Array.from(searchParams.entries()));

visit localhost:3000/?foo=bar#/home

Expected Behavior

[["foo", "bar"]]
is logged

Actual Behavior

[]
is logged

When using a hash router, the only thing react-router knows about is what comes after the hash, so this should work properly using localhost:3000/#/home?foo=bar

@brophdawg11 you're not wrong.
But then how do you interact with query params on URL's that are generated by other services e.g. firebase callback urls?
As their callback url will place the query string before the #/bla
According to the URI spec the query string should come before the hash https://www.rfc-editor.org/rfc/rfc3986#section-4.1
