DOMTokenList list operations

[tomsmalley]

DOMTokenList operates on lists, but it appears that it shouldn't.
https://developer.mozilla.org/en-US/docs/Web/API/DOMTokenList

Intended use:

$0.classList
["ui", "sticky", value: "ui sticky"]
$0.classList.add('one','two');
undefined
$0.classList
["ui", "sticky", "one", "two", value: "ui sticky one two"]

But calling from haskell

stickyList <- Element.getClassList sticky
DOMTokenList.add stickyList ["one", "two"]

results in

$0.classList
["ui", "sticky", "one,two", value: "ui sticky one,two"]

I don't think this is what you would expect upon calling the add function, although the same happens if you were to do $0.classList.add(['one','two']). The only reason I think this behaviour is bad is that the function is defined to take a list explicitly, so you might expect the first behaviour instead of the second.

Since this is all generated code I have no idea if it is at all fixable, of course the workaround is simple enough: just call DOMTokenList.add individually for each addition.
