What is #shadow-root, and why does it put display none on my font awesome classes? [duplicate]

Question

Why does the shadow-root styles put display none on my .fa-xxx classes?

The shadow-root thing adds the classes I use to a display none pile, but only the specific ones I add!

I'm using PHP to include navigation, footers and such, but these don't get effected by it. For example it works just fine in my navigation. There it displays the font just fine.

What is causing this, and how do I control it?

Do you have AdBlock extension installed? That might hide your elements.
