Re: [csswg-drafts] [css-grid] making percentage grid-gaps zero for the purpose of intrinsic sizing doesn't make sense

Sure, I can understand that, but what I suggest is a small amendment
that would be a major benefit for authors.  And it makes percentages
here more consistent with how they work in general.

Note that I'm not suggesting making any changes to the track sizing
algorithm.  It's a fairly simple additional step after that.
(maybe at the end of ยง5.2. "Sizing Grid Containers"?)

It might be possible to improve percentage min track sizing too.
One idea is that we could also check that each track with a percentage
min sizing that its current size (from 'auto') is at least the size
it would have using the intrinsic size as the percentage basis.
If not, increase the intrinsic size so that each minimum will be met.
(This is just a heuristic nudge though, I'm not suggesting we should
re-run the track sizing algorithm again after that.)

I'll discuss this with @dbaron et al.
