What did you expect to happen?
I'm expecting this to work as defined in the docs

    "vue/attribute-hyphenation": [2, "never", {
      "ignore": ["enter-active-class"]
    }],

What actually happened? Please include the actual, raw output from ESLint.

	Configuration for rule "vue/attribute-hyphenation" is invalid:
	Value ["never",{"ignore":["enter-active-class"]}] should NOT have more than 1 items.

same here. Specifying {"ignore":["some-things"]} but it all says should NOT have more than 1 items
