Having global Head alters TopBar style

[sttic]

It seems like having global Head (in _app) alters the classes/styling applied to TopBar components and potentially more.

It was introduced in 0718853 and the most obvious effect is the Social icons becoming smaller. A new class is being applied to it that overrides the width that was previously set.

Edit: I'm not exactly sure but I feel like it's something to do with trying to set the fontawesome width with emotion/styled instead of using its props. Idk why the issue didn't appear earlier though 🤷
