subtract its outer flex base size from its [[#intrinsic-item-contributions|max-content contribution]] size.
- If that result is not zero, divide it by (if the result was positive) its flex grow factor floored at 1,
- or (if the result was negative) by its scaled flex shrink factor, having floored the flex shrink factor at 1.
+ If that result is positive,
