Describe the bug
Extension method color depends on list type.

To Reproduce

void main() {
  var list = <dynamic>[1, 2, 3];
  list[0].equals(1); // <- blue

  var list2 = <int>[1, 2, 3];
  list2[0].equals(1); // <- yellow
}

extension ExpectExtension on Object? {
  void equals(Object? value) {
    assert(this == value);
  }
}

Expected behavior
Same colors.
