Grid Vaadin 8 can't change row size

I’m working with 8.1 and my own theme but can’t figure out how to change the height of the rows, I want 100px. Here is my theme and code.

The cell text does turn red but the row remains at 38px.

Please help. Thanks.

@import "../valo/valo.scss";




@mixin mytheme {

  @include valo;
      .v-grid-cell-local {
           height: 100px;
           color: red;
    }
  

    .v-grid-row-local {
        height: 100px;
        color: blue;
    }

    .v-label-local {
        height: 70px;
    }
}
@Theme("mytheme")
public class MyUI2 extends UI {
    private static final long serialVersionUID = 8710201423597120300L;

    @Override
    protected void init(VaadinRequest vaadinRequest) {
        final VerticalLayout layout = new VerticalLayout();
        layout.addComponent(makeGrid());
        setContent(layout);
    }

    ClassResource face = new ClassResource("face.png");

    private Grid<User> makeGrid() {

        List<User> users = new ArrayList<>();
        User u = new User();
        u.name = "test test";
        u.dayOff = "yes off";
        users.add(u);
        
        u = new User();
        u.name = "test2 test2";
        u.dayOff = "no off";
        users.add(u);
        
        u = new User();
        u.name = "test3 test3";
        u.dayOff = "no off";
        users.add(u);
        

        Grid<User> userGrid = new Grid<>("Rate your favorite Countries");
        userGrid.setItems(users);

        userGrid.addColumn(user -> { 
            Label l = new Label(user.getName());
            l.addStyleName("v-label-local");
            return l;
        }, new ComponentRenderer()).setCaption("Name").setId("nameId");
        
        userGrid.addColumn(user -> new Label(user.getDayOff()), new ComponentRenderer()).setCaption("Day off").setId("dayOffId");
        
        Column<User, ?> column = userGrid.getColumn("nameId");
        column.setStyleGenerator(user -> {
            return "v-grid-cell-local";
        });
        
        column = userGrid.getColumn("dayOffId");
        column.setStyleGenerator(user -> {
            return "v-grid-cell-local";
        });
        
        userGrid.setStyleGenerator(user -> "v-grid-row-local");
        
        return userGrid;
    }

    class User{
        String name;
        String dayOff;
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String getDayOff() {
            return dayOff;
        }
        public void setDayOff(String dayOff) {
            this.dayOff = dayOff;
        }
    }
    
    @WebServlet(urlPatterns = "/*", name = "MyUIServlet", asyncSupported = true)
    @VaadinServletConfiguration(ui = MyUI2.class /* entry point into the UI */, productionMode = true)
    public class MyUIServlet extends VaadinServlet {
        private static final long serialVersionUID = -6170475567092457100L;
    }

}

In version 8.1 there should be a method Grid.setRowHeight for setting the row height programmatically.
