Intervention reportsLimited availability

Intervention reporting sends a report to a URL nominated by the Reporting-Endpoints header when the browser has not honored an application's request, contrary to specified behavior, such as for security or privacy reasons.

Not yet supported in all major browsers — check the table and provide a fallback.

Discouraged: Specification authors no longer define browser behaviors as "interventions" or "non-interventions."
