Repro case with a master build: https://codesandbox.io/s/stoic-mcnulty-dhygf?file=/src/App.js:668-703

Expected: we see content after a second.
Actual: fallback never resolves.

This happens in a sequence of:

1. Normal update
   - which suspends
2. Idle update
   - which also suspends
3. An unrelated normal update immediately followed by a ping (so they're batched)
   - here, we decide to stay on fallback, but should've shown the content

If you remove `_setVersion(v => v + 1);` on line 44 then the issue goes away.
return (
        <>
          <Text text={text} />
          <Suspense fallback={<Text text="Loading..." />}>
            {shouldSuspend && <AsyncText text="B" />}
          </Suspense>
        </>
      );
    }
    const root = ReactNoop.createRoot();
    ReactNoop.discreteUpdates(() => {
      
      root.render(<App text="A" />);
