[From the Profiler docs](https://reactjs.org/docs/profiler.html#onrender-callback):

> The Profiler requires an onRender function as a prop. React calls this function any time a component within the profiled tree “commits” an update.

However, given:

```jsx
import React from 'react'
import ReactDOM from 'react-dom'

function Counter() {
  const [count, setCount] = React.useState(0)
  const increment = () => setCount(c => c + 1)
  return <button onClick={increment}>{count}</button>
}

function App() {
  return (
    <div>
      <React.Profiler
        id="counter"
        onRender={() => console.log('called')}
      >
        <div>
          Profiled counter
          <Counter />
        </div>
      </React.Profiler>
      <div>
        Unprofiled counter
        <Counter />
      </div>
    </div>
  )
}

ReactDOM.render(<App />, document.getElementById('root'))
```

I'm getting a log when I click on the unprofiled counter.

Am I misunderstanding this API, or is this a bug?
if (renderState === null) {
    workInProgress.memoizedState = ({
      : ,
      rendering: null,
      : ContentRow,
      : ,
      Expiration: 0,
      Mode: Mode,
      Effect: EffectBeforeRendering,
    }: SuspenseListRenderState);
  } else {
     
    renderState. = ;
    renderState.rendering = null;
    renderState. = ContentRow;
    renderState. = ;
    renderState.Expiration = 0;
    renderState.Mode = Mode;
    renderState.Effect = EffectBeforeRendering;
  }
}
 This can end up rendering this component multiple passes.
 The first pass splits the children fibers into two sets. A head and .
 We first render the head. If anything is in fallback state, we do another
 pass through beginWork to rerender all children (including the ) with
 the force suspend context. If the first render didn't have anything in
 in fallback state. Then we render each row in the  one-by-one.
 That happens in the completeWork phase without going back to beginWork.
