Answer 1

I confess I do not know WHY this works but it seems that Chrome has a bug when dealing with CSS columns...but based on this ANSWER adding a Z translation AND -webkit-margin-top-collapse:discard; to the image might offer some relief.

ul li:hover img {
  transform: scale(1.4) translateZ(0);
  transition: transform 0.6s ease 0s;
  -webkit-margin-top-collapse:discard;
}
