[bug] Download arrows in Firefox.

[Neoares]

I think the image talks by itself. Tested on FF 60.0b1 and FF 59.0.1. In Chrome works fine.

And this is how they should look:

Thanks! I can reproduce it
It's also an issue for webdash-npm-scripts, there should be an arrow in the small square

I just checked if it's an upstream issue, but iron-icons is displaying properly on firefox
I'll take a look soon

First icon is not an iron-icon, it's simply an inlined SVG
so it'll probably be easier to fix
however 2nd one is an iron-icon

This seems to be a polymer issue tracked in Polymer/polymer#1182
