Bug 1479756 - Clip the overlapped header tick label. r=daisuke

This patch will clip the overflowed tick label. In order to check the width,
this patch add the max-width into tick label element.

Furthermore, componentWillReceiveProps is deprecated from React 16.3.
So this patch will use componentDidUpdate instead of it.
