Okay, we added some text explaining that for the purpose of calculating
intrinsic sizes, percentages are treated as indefinite within min-size: auto
   "For the purpose of calculating an intrinsic size of the element
   (e.g. the element’s min-content size), this value causes the
   element’s width/height to become indefinite (even if e.g. its
   width property specifies a definite size). Note this means that
   percentages calculated against this size will be treated as auto."

CC Rossen and dholbert for correctness-checking. :)
Let us know if this doesn't quite make sense.
