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.
foo = this;
        if (this.state.suspend) {
          Scheduler.unstable_yieldValue('Suspend!');
          throw thenable;
        }
        return <Text text="Foo" />;
      }
    }
    const root = ReactNoop.createRoot();
    await ReactNoop.act(async () => {
      root.render(<App />);
    });
    expect(Scheduler).toHaveYielded(['Foo']);
    await ReactNoop.act(async () => {
      foo.setState({suspend: true});
      
      
      
      expect(Scheduler).toFlushAndYieldThrough(['Suspend!']);
      
      
      foo.setState({suspend: false});
    });
    expect(Scheduler).toHaveYielded(['Foo']);
    expect(root).toMatchRenderedOutput(<span prop="Foo" />);
  });
  
  it('should not render hidden content while suspended on higher pri', async () => {
    function Offscreen() {
