To me, it seems that changing line (17) will have no impact; you will
in any case get 3 zero-width columns at 50px gap. The only differnce
is that line 18 will set it to three, rather than line 24.

I think we must allow zero-width columns. This will also occur when
'column-count' approaches infinity. But we probably don't want to
allow 'column-width: 0'. In the editor's draft, I have clarified that
zero is an acceptable computed value for 'column-count'.
