CSS Multicol 2 says that "an element whose column-width, column-count, or column-height property is not auto establishes a multi-column container".
This implies that setting only column-height is enough to make something a multicol container. But later on in the spec, the (normative) pseudo-algorithm contains this code:
(01) if ((column-width = auto) and (column-count = auto)) then
(02) exit; /* not a multicol container */
One of the two is wrong, and the rest of the pseudo-algorithm also does not seem equipped to handle a column-height-only multicol container.
I assume this is fallout from column-height only being added in the level 2 spec.
