Canonical link doesn't accept search params on root path

Link to the code that reproduces this issue

https://codesandbox.io/p/github/ioancruso/nextjs-bug-reproduction/main

To Reproduce

1. Start the aplication
2. Go to main page and press the button to go to a random page.
3. Check the link tag with rel="canonical"

Current vs. Expected behavior

Since I've set the metadataBase URL in the layout and specified the path in the page file, the link should include the path along with the search parameters I've set, but it doesn't happen. It only displays the default metadataBase URL. This issue arises only when the path contains search parameters (e.g., "?something=something"). The strange thing is that it only occurs on the root path ("/"). I've included another page in a folder, and there the path is shown correctly.
