Transitions of <MagicMove.Text> inside another <Text> is not supported

This doesn't work:

```jsx
<Text>
  <Text>Hello</Text>
  <MagicMove.Text>Magic Move</MagicMove.Text>
  <Text>, how are you doing?</Text>
</Text
```

It seems that text inside Text is layed out differently on iOS (Android hasn't been verified yet), and cannot be measured in this way.
