CSS WG has agreed to modify the spec so now the transferred size is used (if it exists) independently if it's bigger or smaller than the content size. See: https://github.com/w3c/csswg-drafts/issues/1149 The spec text (https://drafts.csswg.org/css-grid/#min-size-auto): "The automatic minimum size for a grid item in a given dimension is its specified size if it exists, otherwise its transferred size if that exists, else its content size"
