The change is inspired by undici code itself, where they concatenate the pathname with the search attribute.

Thanks for the PR! This looks great to me. I will run the e2e tests for a sanity check and merge it once everything passes. 👍🏼

I think this breaks anyone who's currently doing matching against single query params

Yes, I was concerned that would break - if there's a test to ensure it doesn't, I'm happy!

[edmundhung]

Makes sense 👍🏼 Added tests on #7682
