Implement sticky user activation carry-over for same-origin navigations, as proposed in whatwg/html#11454. When a page navigates to another same-origin page, sticky activation(hasBeenActive) should be preserved. However, sticky activation should NOT be carried over when the navigation involves a cross-origin redirect(A -> B -> A2), to prevent confused deputy attacks. Upstream WPT tests: - html/user-activation/navigate-to-sameorigin.html (verifies sticky activation is preserved across same-origin navigations) - html/user-activation/navigate-to-crossorigin-redirect.html (verifies sticky activation is NOT preserved through cross-origin redirects) Related: - Bug 312241 (WPT test import, resolved) - Bug 312719 (eventSender popup window support, required for running the tests) - Spec PR: https://github.com/nicolo-ribaudo/tc39-proposal-structs/pull/11454
