multicol-zero-height-001-ref.xht produces 1px tall fragmentainers.

The fragmentation spec says that fragmentainer heights should never be shorter than 1px [1], so that we don't get stuck without content progress. This means that if the multicol container's content box height is 0, fragmentainers inside it will still be 1px. The ref depended on incorrect behavior in Presto, where floats would never be fragmented.
