Inline method doesn't properly handle target of PrefixedIdentifier

[stereotype441]

Starting with the following code:

abstract class C {
  List<String> get myList;

  String get _first => myList.first;

  test() => _first.isNotEmpty;
}

Active the "inline method" refactoring on the method _first.

Expected result:

abstract class C {
  List<String> get myList;

  test() => myList.first.isNotEmpty;
}

Observed result:

abstract class C {
  List<String> get myList;

  test() => _first.myList.first; // Undefined name '_first'
}
