Describe the Bug

Type error when passing size as string specifying units.

<>
  {icon && <Icon name={emojiName} size="1.999em" />}
</>
{/* error ts(2322): Type 'string' is not assignable to type 'number'. */}

What's the expected result?

Expected: make size?: string to be able to specify units aka rem, em, px, etc. similar to real SVG width/height attributes
