- * According to the spec the `default origin` for an iframe is its `declared
- * origin`, meaning, the src attribute:
- * https://w3c.github.io/webappsec-permissions-policy/#declared-origin
- * The `default allowlist` for 'fullscreen' is "'self'":
- * https://fullscreen.spec.whatwg.org/#permissions-policy-integration
- * And 'self' means:
- * 'self'
- * The feature is allowed in documents in top-level traversables by default,
- * as well as those in child navigables whose document is same origin with
- * its parent’s document, when allowed in that Document. It is disallowed
- * by default in child navigables whose document is cross-origin with its
- * parent’s document.
- * (https://w3c.github.io/webappsec-permissions-policy/#default-allowlists)
- * Therefore a navigated iframe must not have fullscreen permissions unless
- * the new origin matches the origin in the src attribute and is same-origin
- * with the embedding page.
