  • RegExp.make`${/()/}\1` returns /(?:())(?:)/ - The backreference was incorrectly removed.
  • RegExp.make`\1${/()/}()` returns /\1(?:())()/ - Should use \2 to maintain its reference to the same group in the top-level pattern and not be affected by the interpolated pattern (even though it always matches an empty string in this position).
