Unexpected `AsyncFiberException` error when using managed runtime

[OliverJAsh]

What version of Effect is running?

Latest

What steps can reproduce the bug?

https://effect.website/play#ab0825c0bc38

import { Effect, Layer, ManagedRuntime } from 'effect';

const runtime = ManagedRuntime.make(Layer.empty);

runtime.runFork(Effect.async(() => {}));

// AsyncFiberException: Fiber #3 cannot be resolved synchronously. This is caused by using runSync on an effect that performs async work
runtime.runSync(Effect.sync(() => {}));

What is the expected behavior?

No error, to match the behaviour of not using a managed runtime.

What do you see instead?

See above.
