#4122
c915581Thanks @github-actions! - FixTypeError: handlePageUnload is not a functionthrown on page unload when a version-skewed lazy-loaded surveys chunk produces a survey manager whose prototype lackshandlePageUnload. The delegated call inPostHogSurveys.handlePageUnload()now guards the method as well as the receiver.

562ceebThanks @posthog! - Session recording no longer crashes on startup when a CDN-loaded recorder chunk runs against an older bundled core. Calls intoSessionIdManager.on/onSessionIdare now guarded so a core without those methods degrades gracefully instead of throwing aTypeErrorduringstart().
