Ignore comment bug

[FMorschel]

I'm not sure if this is a bug on the quick-fix, analyzer or both (less likely).

Repro:

// ignore_for_file: unused_element_parameter, this is a comment on why

class _C { // unused_element
  _C({int? i});
}

The unused_element will have a quick-fix to ignore for the file. But it will append , unused_element after why. In that case, the quick-fix resolves nothing.

That's definitely a bug on the quick fix.
