Resolve incorrect position for Ellipsis when mixed LTR & RTL languages and set layout direction RTL

Here's sample code for issues:
    //Case 1:
    TextLabel textLabel = TextLabel::New("Projector استكشاف");
    textLabel.SetProperty(Dali::Toolkit::DevelTextLabel::Property::ELLIPSIS, true);
    textLabel.SetProperty(Dali::Toolkit::DevelTextLabel::Property::ELLIPSIS_POSITION, Dali::Toolkit::DevelText::EllipsisPosition::END);
    textLabel.SetProperty(Dali::Actor::Property::LAYOUT_DIRECTION, LayoutDirection::RIGHT_TO_LEFT);
    textLabel.SetProperty(Actor::Property::SIZE, Vector2(145.0f, 60.0f)); // minimize width until the ellipsis comes between two languages

    //Case 2:
    TextLabel textLabel = TextLabel::New("استكشاف Projector");
    textLabel.SetProperty(Dali::Toolkit::DevelTextLabel::Property::ELLIPSIS, true);
    textLabel.SetProperty(Dali::Toolkit::DevelTextLabel::Property::ELLIPSIS_POSITION, Dali::Toolkit::DevelText::EllipsisPosition::START);
    textLabel.SetProperty(Dali::Actor::Property::LAYOUT_DIRECTION, LayoutDirection::RIGHT_TO_LEFT);
    textLabel.SetProperty(Actor::Property::SIZE, Vector2(145.0f, 60.0f)); // minimize width until the ellipsis comes between two languages
