Expected Behavior

Icon only buttons should render with same dimensions as icon + label / label-only buttons.

Actual Behavior

In Safari, extra dimension is added above the svg, even though the SVG's dimension is square. This causes icon-only buttons to have different dimensions that other buttons. Depending on the theme, this effect is more dramatic than others.
