Re: [csswg-drafts] [css-grid-3][masonry] item-flow row vs. column in masonry layouts (#12803)

I’m not following how grid-lanes is 1D. We only use one dimension of lanes, but items are placed in two dimensions.

Could there be something in a B1a where `grid-auto-flow` does **not** determine the grid-lanes direction? If you set `grid-template-columns` you get waterfall, if you set `grid-template-rows` you get masonry, and if you set both you get waterfall (picking that as the default).

Then `grid-auto-flow` would only be used to reverse things.
