+            Patch these functions to always check the layout state for a zero

+            doing column balancing and don't have a height set yet.

+            The function for deciding whether the logical height of the columns was
+            known was checking for a zero computedColumnHeight. However, a column set
+            can legitimately compute a zero column height, and with the fix to examine
+            the layout state, this bug was exposed.
+
+            The fix is to add a new variable that caches whether or not the column height
+            has been computed, so that even if it computes to zero, we aren't fooled.
