Current baseline already contains some failures, but glib ports are presenting some different failures when the popup policy is SAME_SITE and the iframe policy is CROSS_ORIGIN, and vice versa.

Namely, in comparison to the mac port, when opening the popup with window.open, it seems glib ports correctly shield the DOM access, but leaks cross-origin access.
