Bug 1657437 - Don't treat lone CRs as segment breaks. r=jfkthame 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.
