And not only that, also the text in the algorithm needs to be updated
too [3]:
"When the grid container is being sized under a min-content constraint,
 a track with a flexible min track sizing function is treated as if
 its min track sizing function was min-content for the purposes
 of this step."

But now a "track with a flexible min track sizing function" is invalid.
