Icon: all icons fixed width

[billgil]

if an Icon is flexed with another element and the page or its container gets too tight, it gets very tiny, this should not happen

problem

fix

add a div around the Icon and use

width: props.width
min-width: props.width
height: props.height
min-height: props.height

please make this the default behaviour of Icon so it never shrinks in small spaces. Maybe it would be nice to offer an isResponsive props for people who like the bug as a feature
