Details

Steps to reproduce:

In Firefox if you navigate an iframe to about:blank?query#fragment, the iframe is seen as cross-origin when it should be considered same-origin, since it "matches about:blank" 1. Chromium and Safari agree in this case. See https://github.com/whatwg/html/pull/9558 and https://github.com/whatwg/html/issues/9488.

Moving it to Core.
If this is not the correct component, please feel free to change it to a more appropriate one.
