Re: [heycam/webidl] Define [[OwnPropertyKeys]] of legacy platform objects (#402)

> I am concerned about the extent to which it matches implementations, especially with regard to ordering

While I did write this PR to match what implementations are doing, I would agree that there are a lot of corner cases, like index prop names that are not array index prop names ([2^32, 2^53)), assigning array index prop names to objects that don't support indexed properties (and vice versa), and symbols. To that end I'd definitely agree that there should be tests.

Can you point out the update you are referring to?

Is there a specific section in WPT for Web IDL compliance or should I look into adding these tests to the section of the tested interface (e.g. `HTMLCollection`)?
