Re: [csswg-drafts] [css-grid] Resolving percentage heights of grid items during min-content sizing

> So the base sizes of the tracks should be 0 auto 0

@fantasai that statement makes no sense. Base sizes are the result from the Track Sizing Algorithm - they  can't be "auto".  They are always a definite size. I'm assuming you mean "the block-size of the grid item after it is flowed in a containing block (CB) that has an inline size of 200px". So, I assume you mean "0 ~200px 0".

Also, I don't understand why  you think the base size should be zero in the third test. You are correct that [Automatic Minimum Size](https://drafts.csswg.org/css-grid/#min-size-auto) doesn't apply, but that doesn't make the min-content contribution zero - it's still "the block-size after flowing it", which in this case is 204px (the CB inline size is definite (200px), which makes the `<figure>` width 200px which provides a CB inline size for the image which becomes 200px in height, which makes the `<figure>` grid item have block-size 204px in Nightly because the `<figure>` (a block) baseline adds 4px (adding `vertical-align:top` makes it 200px). I can't find any spec that says that `overflow != visible` (and a block-size that "behaves as auto") on non-replaced blocks implies they have zero min-content contribution.  Please point it out if I missed it, thanks.
