Don't treat lone CRs as segment breaks.

That prevents preceding whitespace from getting collapsed.

When there's a single lone CR (so `a\rb`) our behavior here diverges
from Chrome's but matches Safari's. We treat it as ZWSP.

That matches the initial resolution of [1], but then there have been
various doing and undoings of that resolution, so it's not totally clear
to me what the correct behavior per spec should be. I think "treat it as
other control character"? But I haven't dug into what that implies, so
for now I've just kept behavior there as-is.
