overflow-y:scroll in .content doesn't let scroll using keyboard

[sidvishnoi]

Using Firefox Developer Edition on Ubuntu 16.04
Pages: /playground/*
Issue: If someone clicks inside the content div and then tries to scroll using keyboard, one cannot scroll as the .content has overflow-y: scroll. (See screenshot)

Quick fix: src/styles/layout/_layout.scss : .content { overflow-y: hidden; }

Also, the blank scrollbar doesn't look good either and is redundant.

Other than that, this works fine in Chrome but Firefox doesn't let scroll in parent container after focusing on scrolling child container with no more scroll space (Issue?)

I'm using Firefox 57 on Windows 10 and can see the vertical scroll as well. It also behaves the way @sidvishnoi described it.

Is there a reason for having a scroll on the .content?
