The hint will auto show when click the "Next Challenge" if the previous challenge is showing the hint

[CassieRan]

For Example: https://beta.reactjs.org/learn/keeping-components-pure#challenges
1.At the first challenge, click "Show hint", the hint of the first challenge will show
2.Click "Next Challenge" button, it comes to the second challenge, and the hint of the second challenge is showing
If switching challenge through click the tab bar, it looks great.
