Automatic update from web-platform-tests [css-grid] Always consider baseline shim for the minimum contribution Before this patch, the shim used for baseline alignment is not taken into consideration when calculating the minimum contribution of a grid item if its preferred size is auto, its minimum size is auto, and the max track sizing function is a fixed small value. In this case, the auto minimum size can produce a smaller track than if it was 0. The specification needs to clarify how baseline shims interact with minimum contributions (https://github.com/w3c/csswg-drafts/issues/3660), but the above doesn't make sense.

Also checks that the shim is used again when clamping the automatic minimum size to less than or equal to the stretch fit into the grid area.">
