Subtle overlap below "Table of Contents" in right sidebar

[saforem2]

I noticed that there's a box that seems to faintly overlap with the links immediately below the "Table of Contents" in the right sidebar.

its definitely subtle, but you can see it in the screenshot below:

I believe (part) of the issue is coming from the changes to the .md-nav { ... } rule here in here in our stylesheet:

user-guides/docs/stylesheets/alcf-extra.css

Line 206 in 7e9e624

.md-nav {

which are making this md-sidebar md-sidebar--secondary overlap with the text below.

Turning these off seems to fix it:

/*
.md-nav {
  font-size: 15px;
  line-height: 1;
}
*/

but I'm not sure if there's a reason these were being set in the first place.

If not, we should just remove the .md-nav rule from our alcf-extra.css
