fetcher.load throws are only caught at Root's boundary?

[ecrvich]

I have a resource route with a loader, a CatchBoundary, and an ErrorBoundary. It also has a default function that just returns an empty React fragment (so that it can also function as "real" child route if needed).

If I call that route with Link, that route's Catch/ErrorBoundary is correctly called when either a Response or Error is thrown. However, if I call that same route with fetcher.load() instead (exact same code in all respects otherwise), the thrown Error or Response will ONLY result in the Root element's Catch/ErrorBoundary being called.

Is that working as designed, or a bug? Or is there some trick that must be employed with fetcher.load() to get that route's Catch/ErrorBoundary to be called?
