Why are some of the secondary options not working for the rules in my .stylelintrc?

Question

I am trying to format my css so there's no more than one empty line between lines, but I don't want that to apply to comments. The documentation for stylelint has a secondary option that should make this easy, but for some reason it isn't working.

Here's the rule:

"max-empty-lines": [
      1,
      {
        "ignore": [
          "comments"
        ]
      }
    ],

And here's the rest of my .stylelintrc for reference:

  "rules": {
    "at-rule-empty-line-before": "always",
    "at-rule-no-unknown": true,

  }
}

You are using the secondary option correctly as this demo shows:

{
  "rules": {
    "max-empty-lines": [1, {"ignore": ["comments"]}]
  }
}

/* comment 


*/

a {}


b {}

Gives only one error on line 8:

8:1 error Expected no more than 1 empty line (max-empty-lines)

If you aren't seeing this behaviour locally, I suggest reporting a bug in the Stylelint issue tracker.
