`min-width: 0` on .col has too much side-effects

Closes #30852 (closed)

For some reason I cannot revert the merged commit. So let's simply drop it.

Flexible items are flexible, so in order to fix what #30049 tried to fix: either use fixed width on pre, or let it wrap by using:

.col > pre {
  white-space: pre-wrap;
}
