Let's just do this one unconditionally? I'd rather have simpler code than the presumably-trivial performance gains of invoking slice.

(Facebook's toArray corroborates this story: https://github.com/facebook/react/blob/master/src/vendor/core/toArray.js says "IE < 9 does not support Array#slice on collections objects".)

Oh, one thought: if we force edge compatibility mode, maybe that fixes this?

Are these actual ie8 browsers? (We should force edge anyways)

I tested it with a real, live IE8 browser in "IE8 Standards" mode.
