[css-grid] max<min comparison in minmax()

[Loirooriol]

From https://drafts.csswg.org/css-grid/#valdef-grid-template-columns-minmax

• minmax(min, max)
  Defines a size range greater than or equal to min and less than or equal to max. If max < min, then max is ignored and minmax(min,max) is treated as min.

It's not clear whether the last sentence means that minmax(min,max) should be treated as min before starting the sizing algorithm, i.e. that both the initial min and max track sizing functions should be min, or whether it refers to

In all cases, if the growth limit is less than the base size, increase the growth limit to match the base size.

which keeps appearing along the algorithm, and the initial min and max track sizing functions will still be the specified values.

In the former case, please define how to perform the comparison if min and max are not both <length> or resolveable <percentage>.

It's the latter. The point of the descriptions up front is so that we know what we're trying to do. Putting the entire algorithm into the description of each value of the property isn't workable.

[Loirooriol]

That's what I assumed, but the text is normative so it's confusing. I suggest moving it into a note, and maybe using "will" instead of "is" to hint it will be defined in detail later.

OK, tweaked the wording. LMK if it looks OK now.

Still doesn't seem 100% clear to me, but now it's better, thanks.
