pub fn loopback_allowed(
url: &str,
opener_url: &str,
own_origins: &[String],
) -> boolExpand description
May a page on loopback open a window to url, also on loopback? Only
on its own origin (a local dev site opening its own popup), and never one
of AgentMux’s own (own_origins: its frontend and srv), which a page
must not be able to put in front of the person
(native-popups spec §3).
