Highlight finished download(s) via style class (#149)

![screenshot from 2018-11-01 16-07-25](https://user-images.githubusercontent.com/1204189/47860187-438cf180-ddf0-11e8-9733-c8fed7e1419c.png)

After looking at the downloads popover the style class is removed and no longer visually demanding attention.

I thought the "needs-attention" style class might be appropriate here but it doesn't seem to work since it's only an animation, so I opted for the "suggested action" instead.
