[Web API type definition issue] securitypolicyviolation event in WorkerGlobalScope should be typed as SecurityPolicyViolationEvent

Summary

Missing Type for SecurityPolicyViolationEvent in WorkerGlobalScope

Expected vs. Actual Behavior

securitypolicyviolation event in WorkerGlobalScope should be typed as SecurityPolicyViolationEvent

According to the MDN documentation, the securitypolicyviolation event in WorkerGlobalScope should provide a SecurityPolicyViolationEvent.

Currently, TypeScript types this event as a generic Event, which loses all the properties specific to SecurityPolicyViolationEvent such as documentURI, blockedURI, violatedDirective, effectiveDirective, etc.

It would be helpful if TypeScript provided proper typings so that developers can access these properties safely, for example:

self.addEventListener('securitypolicyviolation', (event: SecurityPolicyViolationEvent) => {
  console.log(event.violatedDirective);
});
