Format prop elements

`r-e-t-j-s` (version `14.3.2`) formats child elements pretty well, like so:

```javascript

```
... However, elements passed as props get the `inline` -treatment:
```javascript
Input:}
onClear={handleFunction}
/>
```
**maxInlineAttributesLineLength** seems to have no effect here. Is there a way to get "prop elements" to get pretty-printed in the same way as regular `children` are? Or am I simply doing something wrong?

Start by reproducing the JSX formatting example with react-element-to-jsx-string 14.3.2 and maxInlineAttributesLineLength enabled. Trace how the formatter handles elements supplied through props versus regular children, then verify that prop elements receive the requested multiline formatting without changing the existing child-element output.
