mobx observable and checking items against PropTypes.array

[cotko]

Hi,

you specified that items should be an array but since this is a mobx related module, it would probably make sense that observable lists can be passed as items as well (I'm currently getting error notices because of this)?

static propTypes = {
      items: PropTypes.oneOfType([
          PropTypes.array,
          PropTypes.object
      ]).isRequired,
      itemHeight: PropTypes.number.isRequired,
      itemBuffer: PropTypes.number,
};
