== [css-lists] Serialization of counter-increment/set/reset ==
As discussed [recently](https://github.com/w3c/csswg-drafts/issues/3687#issuecomment-516981741), `counter-reset` etc. can have repeated counter names.

For set/[reset](https://drafts.csswg.org/css-lists-3/#counter-reset), only the last value for each name is relevant. For [increment](https://drafts.csswg.org/css-lists-3/#increment-set), only the total value for each name is relevant.
For serialization of specified and computed values, should implementations preserve repetitions? 

For distinct names, should order be preserved, or should we use lexicographic order, or is order arbitrary?

Suppose we have
`counter-reset: foo 1 bar 2 foo 3 bar 4;`

Should `getComputedStyle().counterReset` return `"foo 1 bar 2 foo 3 bar 4"` or `"foo 1 foo 3 bar 2 bar 4"` or `"bar 2 bar 4 foo 1 foo 3"` or `"foo 3 bar 4"` or `"bar 4 foo 3"`, or are either of the last two OK (e.g. if an implementation uses hash tables) ?
