Definition of "collection" is nonsensical

[Loirooriol]

https://w3c.github.io/webdriver/#dfn-collection

A collection is an Object that implements the Iterable interface, and whose:

• initial value of the toString own property is "Arguments"
• instance of Array
• instance of DOMTokenList
• ...

Problems:

• Expressions like "whose [...] instance of Array" are ungrammatical
• It's unclear whether all conditions of the list must hold, or a single one suffices
• Arguments objects do not have a toString own property. They inherit a toString property but its value isn't a string, it's a function. What this probably meant was Call(%Object.prototype.toString%, collection), but of course this would still consider ({[Symbol.toStringTag]: "Arguments"}) as an Arguments object even if that's not the case.
