Inconsequent string wrapping

## Input

```javascript
const Element = () => (

)
```

## Expected output

```javascript
const Element = () => (

)
```

## Actual output

```javascript
const Element = () => (

)
```

Why is the first `p` element getting wrapped in `{``}`, bet second not. I expect the first to act as the second (ie. not get wrapped.)

Reproduce the JavaScript/JSX example from the issue and trace the repository's React element-to-JSX string formatting entry point. Compare the actual output with the expected output, then add or update coverage so equivalent text is not wrapped inconsistently.
