Custom lineHeight

Can we have the ability to set custom `lineHeight` using `setStyle`?
I saw that `parseStyle` just cuts off all unnecessary props 
`setLineHeight` can accept `lineHeight`, but it will never reach it

Probably we can add something like
```javascript
if (style.lineHeight) {
  parsedStyle.lineHeight = style.lineHeight;
}
```
into `parseStyle`
