The Instant Navigation Testing API already uses a cookie to persist lock state across MPA navigations (page reloads, plain anchor links), since window globals don't survive navigation. Rather than maintaining two parallel mechanisms — a window global for SPA and a cookie for MPA — this makes the cookie the single source of truth for all cases. Playwright sets/clears the cookie directly via the browser context, and the client reacts to changes through the CookieStore API's change event. This removes the window.__EXPERIMENTAL_NEXT_TESTING__ global and the page.evaluate() calls that went with it.
Replace the layered abstraction (Meta, MetaFilter, MultiMeta, ExtendMeta, and 12 category component functions across 5 files) with a single flat function that builds a tags array using explicit if-checks and for-loops. Every meta/link tag is now visible as literal JSX at the call site. OG image/video/audio properties and AppLinks fields are enumerated explicitly rather than iterated generically from object keys. Keys are assigned directly on each element at push time, eliminating the cloneElement keying pass.
… runtime (#90205) The unhandled-rejection module was being bundled into server.runtime.prod.js AND loaded as a standalone file, causing installUnhandledRejectionFilter() to run twice. Each instance captured the other's handler as an underlying listener, creating mutual recursion that overflowed the stack on any unhandled rejection. Fix: Rename to .external.tsx so the webpack config externalizes it from the server runtime bundle. It is now only loaded once from the standalone file by node-environment.ts. Also adds two defensive measures: - A global symbol guard that noops if a second installation is ever attempted from a separate module evaluation (e.g. Jest's module system re-evaluating an already-loaded module in the same process) - A reentrancy guard on the handler that noops if an underlying listener synchronously re-emits 'unhandledRejection'
This PR speeds up the `instant-validation` test suite from 450s down to ~100s. We were wasting a lot of time in `waitForNoErrorToast()`, which ends up waiting almost 15s by default. The trick is to add some debug logs inside app-render to track when instant validation started/ended. If we know that the validation is finished, we can just wait for a short time, because if there were errors, a toast would be displayed very quickly. Note that is a stopgap -- when we add a "Validating..." indicator, we won't have to emit the log and can just wait for the indicator instead. But in the meantime, waiting for the tests is pretty painful, so this is worth doing.
