--- Comment #6 from Alexey Proskuryakov <ap at webkit.org> ---
An author can implement the desired behavior with a zero width joiner (e.g. "sir‍—" for the attached test), among other ways.

While the CSS spec is not fully prescriptive on exactly following UAX #14, it does reference it as the baseline. So WebKit is not wrong here, and given that Chrome behaves in the same way, keeping our current behavior is best for compatibility.
