title: "textAlignVertical" is not a valid style property
body: <p>I am getting an error saying "textAlignVertical" is not a valid style property when attempting to use the 'textAlignVertical' style on a Text element. I've checked the documentation and it says I should be able to use this style property: <a href="https://facebook.github.io/react-native/docs/text.html" rel="noreferrer">https://facebook.github.io/react-native/docs/text.html</a></p>
  
  <p>has anyone else had this issue?</p>
