MDN isn't clear about this (pages haven't been documented), but do toggle and contains support variable number of tokes too?

A comment on https://developer.mozilla.org/en-US/docs/Web/API/Element.classList looks like toggle supports it:

Versions of Firefox before 26 do not implement the use of several arguments in the add/remove/toggle methods. See https://bugzilla.mozilla.org/show_bug.cgi?id=814014

There's W3C on this: http://www.w3.org/TR/dom/#interface-domtokenlist. Which is as well not consistent, but it makes sense this way and is supported by at least Chrome and FF

[w8r]

According to that spec no, .contains() and .toggle() both take only one argument

[w8r]

However, the problem does not end here, IE10+ supports DOMTokenList, but unlike the others(as always), these methods take one argument only, so I came up with this. Should work for FF<26 as well in that case

Sorry for the late pick up, but do we want this merged in?
