Re: [csswg-drafts] [css-grid-3][masonry] Clarify what mixing subgridded items with automatic and definite grid position does (#10926)

We probably should consider this in conjunction with some of the auto-placement improvements in https://github.com/w3c/csswg-drafts/issues/10265.

Here's an example that I think we will want to make work:
* 6 tracks in pairs, type A and type B.
* auto-placed masonry parent grid spanning two tracks, but only allowed to be placed in the pattern A-B, i.e. spanning tracks 1-2, 3-4, 5-6 and not 2-3 or 4-5.

I don't think we have very strong use cases for the OP case to work in a particular way, but for this case we want items that can only end up in A tracks to not contribute to B tracks and vice versa.
