Making icon variation tabs sticky in Version pages

[itayganor]

I was scrolling over the new icons of v5.9.0. They are brilliant!
The only this is, I wanted to view each icon's variations (of solid, regular and light) - so I had so scroll all the way to the top, click one of the tabs, and then scroll bar down to the icon..

I was thinking on an UX solution for it, and I came up with a simple improvement:
Making the tabs container position: sticky;.
It's super simple - although it's an experimental CSS feature, it will function for new browser versions, which most of Font Awesome already use.

You can just add:

{
    position: sticky;
    top: -2em;
    z-index: 1;
    background: rgba(255, 255, 255, 0.95);
}

And turn this:

Into THIS:

Let me know what you think :)
