To Reproduce

The issue is very straightforward. the reproduction is in the repository but is just in this code block:

export const metadata: Metadata = {
  metadataBase: new URL('https://nextjs.org'),
  openGraph: {
    type: "website",
    url: "./?utm=tracking",
    images: ["/images/og-image.png"],
  },
}

The intended use case is to put an open graph metadata containing a tracking code. but it could be any url parameter.
Above renders:

    <meta property="og:url" content="https://nextjs.org"/>

If we use any other (non empty, non-root) url, like this:

export const metadata: Metadata = {
  metadataBase: new URL('https://nextjs.org'),
  openGraph: {
    type: "website",
    url: "./page?utm=tracking",
    images: ["/images/og-image.png"],
  },
}

it works as expected:

    <meta property="og:url" content="https://nextjs.org/page?utm=tracking"/>

Current vs. Expected behavior

expecting the url parameters passed into openGraph Metadata to be preserved.
Alternatively the behaviour should be consistent (and url params dropped for other urls as well) but I doubt that's desirable
