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.

Comienza reproduciendo el comportamiento de la barra lateral en https://reactjs.org/docs/getting-started.html e inspecciona la barra lateral en el viewport del tamaño de un portátil que se muestra en el issue. Se considera terminado cuando se pueda acceder a toda la barra lateral, incluido FAQ, y desplazarla de forma independiente del contenido principal de la documentación.
