Stop down-leveling the nullish coalescing (
??) operator in templates. Depending on the ES version typescript may still down-level it.Note: This does not change the semantics of
??in templates, which currently doesn't match the semantics in TS/JS, as this would be a much more breaking change. The main difference is thata && b ?? cis treated the same asa && (b ?? c)in our template, while its considered invalid in TS/JS
