Infinite horizontal scrollbar on left nav regardless of size?

[Scott Beeson]

It doesn't matter how wide I make the left nav I always have a horizontal scrollbar at the bottom. As you can see, none of the content is wide enough to need a horizontal scrollbar.  

I poked around the inspector and it looks like the padding on this div is the culprit:

It was `padding: 0px 12px`. I forced it to 0 and the scrollbar went away.

Until I get a better fix for this, I'm using the following CSS in a Chrome extension called "Web Override" 

.sc-iQKALj.wBJYs {
    padding: 0 !important;
}
