Layout Issue w/ Duotone

[johnvilsack]

Trying to use duotone icons:

@mixin globe {
	@extend %fa-icon;
	@extend .fas;

	&:before {
		content: fa-content($fa-var-globe);	
	}
}

@mixin globe-duo {
	@extend %fa-icon;
	@extend .fad;

	&:before {
		content: fa-content($fa-var-globe);	
	}
}

generates a failed duotone icon that isn't formatting properly:

I'm currently trying to convert to the duotone icons as well. I'm finding this helpful: https://fontawesome.com/how-to-use/on-the-web/advanced/css-pseudo-elements#with-duotone
