Hi. Seems like names are not consistent in current draft (24 February 2025).
https://drafts.csswg.org/css-sizing-4/#intrinsic-contribution-override
It's min-intrinsic-sizing at the start of section:
5.4. Zeroing Min-Content Size Contributions: the min-intrinsic-sizing property
Name: min-intrinsic-sizing
But it's min-intrinsic-size in the example:
*, ::before, ::after { min-intrinsic-size: zero-if-scroll; }
I assume min-intrinsic-sizing is the correct one.
