Created attachment 473008 [details] reproducer with embedded font The attached file demonstrates the problem: when using a font that supports a variant slashed-zero, and you put "font-variant-numeric: slashed-zero" on an element which has "font-size: 0px", and that element contains a "0", that element takes up whitespace. It only happens for 0. Doesn't happen in Chrome or Firefox. I've tested this with another font which has a slashed-zero variant, specifically Mozilla's Fira from https://github.com/mozilla/Fira/blob/master/woff2/FiraSans-Regular.woff2, and confirmed that it happens with that font as well, so it's not just this specific font.
