IsolatedRendererProvider: failed bundle load is cached permanently

[rgbkrk]

Problem

In isolated-renderer-context.tsx, loadingPromise is cached at module level and never reset on rejection. If the first bundle load fails (network error, 404, etc.), all future mounts/retries reuse the rejected promise and can never recover.

Location

• registry/outputs/isolated/isolated-renderer-context.tsx

Suggested Fix

In the .catch handler, reset loadingPromise = null so a later render can retry:

.catch((error) => {
  loadingPromise = null; // Allow retry on next mount
  if (!cancelled) {
    setState((s) => ({ ...s, isLoading: false, error }));
  }
});

Optional: add bounded retry with backoff for transient failures.

Additional Suggestion

Consider adding error logging in the catch handler for debugging:

.catch((error) => {
  console.error("[IsolatedRendererProvider] Bundle load failed:", error);
  loadingPromise = null;
  if (!cancelled) {
    setState((s) => ({ ...s, isLoading, false, error }));
  }
});
