I've a patch for it

Not sure why this was not automatically updated but this was already fixed.

[css-grid] Use min-size instead of min-content for intrinsic maximums
    
    This was recently modified in the specs, see
    https://hg.csswg.org/drafts/diff/575fb847e29d/css-grid/Overview.bs. We're
    talking specifically about the last change. As it can be seen, in order to
    resolve the intrinsic max track sizing functions, we should use the min-size
    contribution (It used to be min-content contribution).
