Description Ben Nham 2023-12-04 14:36:17 PST 
We want to track how WindowProxy is used across tabs (i.e. via an opener relationship). This can be used to build up telemetry on how useful something like `Cross-Origin-Opener-Policy: restrict-properties` would be on the web (which is a version of COOP that restricts cross-origin WindowProxy to the postMessage and closed properties).
