There is no Scrollbar for Sidebar on official reactjs website.

Hello everyone,
Today I visited React website to learn React by reading docs. But soon I realized that sidebar on react docs page https://reactjs.org/docs/getting-started.html doesn't have a scrollbar. I could not access contents of FAQ from sidebar because sidebar didn't have a scrollbar to scroll and see content of FAQ.

This is how web page looks on my laptop :-

As you can see that I clicked on FAQ in sidebar its content didn't appear because it get's outside of my screen height and I didn't have a scroll bar to scroll.
The one scrollbar that you can see on screen only scrolls content of side page and not scrollbar.

まず https://reactjs.org/docs/getting-started.html のサイドバーの動作を再現し、issue に示されているラップトップサイズの viewport でサイドバーを確認します。FAQ を含むサイドバー全体に到達でき、メインのドキュメントコンテンツとは独立してスクロールできれば完了です。
