Dictionary::values(), Dictionary::keys() and Array::duplicate() create broken Arrays

Dictionary::values(), Dictionary::keys(), Array::duplicate() and maybe other functions create an Arrays that doesn't clear values properly

Dictionary values

Variant action_v = ProjectSettings::get_singleton()->get(String("input/ui_up"));
Dictionary action = action_v;
Array arr = action.values();

or

Variant action_v = ProjectSettings::get_singleton()->get(String("input/ui_up"));
Array arr = ((Dictionary)action_v).values();

or

((Dictionary)ProjectSettings::get_singleton()->get(String("input/ui_up"))).values();

result:

Hint: Leaked instances typically happen when nodes are removed from the scene tree (with `remove_child()`) but not freed (with `free()` or `queue_free()`).

keys

Dictionary d;
Ref<InputEventMouseButton> iemb(InputEventMouseButton::_new());
d[iemb] = iemb;
d.keys();

Array

Array a;
Ref<InputEventMouseMotion> iemb(InputEventMouseMotion::_new());
a.append(iemb);
a.duplicate();
a.clear();

Also this works without leaks:

Array a;
Ref<InputEventMouseMotion> iemb(InputEventMouseMotion::_new());
a.append(a.duplicate());

With leaks:

a.append(((Dictionary)ProjectSettings::get_singleton()->get(String("input/ui_up"))).values());
