--- Comment #1 from Ross Kirsling <ross.kirsling at sony.com> ---
Based on the spec:
https://tc39.es/ecma262/#sec-literals-string-literals
https://tc39.es/ecma262/#sec-additional-syntax-string-literals
https://tc39.es/ecma262/#sec-template-literal-lexical-components
https://tc39.es/ecma262/#sec-static-semantics-template-early-errors

It would appear that our behavior is correct -- namely, it's only non-template strings that should support numeric escapes other than '\0'.

If so, then the thing to do here would be to add test262 cases for the other engines to fix.
