Comment (by TimothyBlynJacobs):

 The patch looks good to me. Right now its return type is really
 `string|null` but is annotated as `string`. Should the function either
 return an empty string when unnecessary, or should the doc be updated. I
 personally prefer returning an empty string, but that's just me.
