Summary Sandbox flags should be snapshotted at start of navigation

Document sandboxing flags should come from the state of the iframe container as the navigation starts. See recent HTML spec change at https://github.com/whatwg/html/pull/5098. There are web platform tests as well, under review at https://github.com/web-platform-tests/wpt/pull/20411 -- Current results are available at https://wpt.fyi/results/html/browsers/sandboxing?label=pr_head&max-count=1&pr=20411 As far as I can tell, Safari's current behavior on those tests is: * sandbox-navigation-timing: Fails because final document is sandboxed. * sandbox-navigation-timing-2: Fails because final document has allow-same-origin. * sandbox-navigation-timing-3: Fails (times out) because final document does not allow scripts.
