Open files/en-us/web/api/navigator/sendbeacon/index.md and locate the “Use pagehide as a fallback” section. Check the current visibilitychange and pagehide guidance against browser support information, then remove the outdated section if confirmed; done means the page no longer presents this fallback as necessary.
