Per the WebDriver BiDi specification, these events should be emitted to notify clients when realm lifecycle changes occur: https://w3c.github.io/webdriver-bidi/#event-script-realmCreated https://w3c.github.io/webdriver-bidi/#event-script-realmDestroyed This prevents BiDi clients from tracking realm changes without polling script.getRealms. Example expected behavior: - Navigate to a page -> script.realmCreated emitted - Navigate away -> script.realmDestroyed emitted for old realm, realmCreated for new - Close context -> script.realmDestroyed emitted Initial implementation will cover window realms for main browsing contexts. Workers and iframes will be addressed in follow-up work.
