PropertySortOrder: use separate_groups without order

[davidenke]

The documentation hints, that

separate_groups is only enforced if a custom order is specified via the order option.

It would be nice, if separate_groups used without order would enforce a capsulated order of groups. Every group would be sorted independently (alphabetically by default).

For example this:

video {
      height: auto;
      left: 50%;
      min-height: 100%;
      min-width: 100%;
      position: absolute;
      top: 50%;
      transform: translate(-50%, -50%);
      width: auto;
}

would become this:

video {
      height: auto;
      min-height: 100%;
      min-width: 100%;
      width: auto;
      
      position: absolute;
      left: 50%;
      top: 50%;
      transform: translate(-50%, -50%);
}

or this:

video {
      min-height: 100%;
      min-width: 100%;

      height: auto;
      width: auto;

      position: absolute;
      left: 50%;
      top: 50%;
      transform: translate(-50%, -50%);
}

I'm not sure I understand this suggestion. How would we know what to put in what group without specifying it through the order?

[davidenke]

Okay, I'll try to improve the explanation:

Per default ungrouped properties are sorted alphabetically. If you now insert a blank line the properties are splitted in two groups (as from the view of the editor) and the order has to remain alphabetically for all properties.

The suggestion is, that both property groups are now sorted indepent alphabetically, if the separate_groups option is used without the order option.

But maybe this suggestion should use a new option...

Ah, I see what you mean now. Arbitrary groups with alphabetic ordering enforced within the groups. I don't think this is possible with the current implementation. I'm happy to accept a PR though.
