The total flex factores need to be a minimum of 1 if any
The total flex factores need to be a minimum of 1 if any

Summary:
The only thing I found in the spec for this change is the following. Not exactly sure if this is the thing this PR is about:

> For each flex item, subtract its outer flex base size from its 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**. This is the item’s max-content flex fraction.

But at least it seems a required change.
