Re: [csswg-drafts] column-fill should behave more similarly in paginated and continuous contexts (#4036)

I sympathize with @dbaron 's request for a cleaner system and symmetry between the continuous and fragmented context.

However, there's a use both for balancing and not balancing the last page even when the height is not constrained. We could change the behavior as suggested and add the missing one later as an extra keyword, but multicol in fragmented media is routinely used in print and pdf formatters, and they implement the spec as it currently is, balancing the columns on the last page even with no height constrain when `column-fill` is `balance`, and not balancing when `column-fill` is `auto`. Given that, this class of user agents are likely to have a compat requirement to keep this behavior, and won't change. I think it would be very unfortunate to fork the language, and for print formatters and browsers to have different behavior on multi-column.

(I have tested Prince and PDFreactor and they are interoperable. Vivliostyle has some bugs, but for that aspect it is interoperable as well.)

All in all, I think we should reject the proposal.
