Grid row's details : RTE displays null instead of a proper value

[anasmi]

Description

When a RichTextEditor used in details of a row, the value set via rte.asDelta().setValue('XY') is ignored and null displayed instead
Note: this seems similar to this task #4551

Expected outcome

RTE has correct value displayed, not null

Minimal reproducible example

@Route(value = "test-view", layout = MainLayout.class)
public class TestView extends FlexBoxLayout {

    record User(String firstName, String lastName) {

    }

    List<User> users = List.of(new User("Julia", "Test"), new User("Bretta", "Test"));

    public static String value = """
        [
          {"insert": "High quality rich text editor for the web\\n", "attributes": {"header":  2}},
          {"insert": "Rich text editor handles the following formatting:\\n"},
          {"insert": "Bold\\n","attributes": { "bold": true, "list": "bullet" }},
          {"insert": "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.\\n", "attributes": { "blockquote": true }},
          {"insert": "Code blocks\\n", "attributes": { "header": 3 }},
          {"insert": "<vaadin-rich-text-editor></vaadin-rich-text-editor>\\n", "attributes": { "code-block": true }}
        ]
        """;

    public TestView() {
        Grid<User> grid = new Grid<>(User.class, false);
        grid.addColumn(User::firstName).setHeader("Name");
        grid.addColumn(User::lastName).setHeader("last name");

        grid.setItemDetailsRenderer(createPersonDetailsRenderer());
        grid.setItems(users);

        add(grid);
    }

    private static ComponentRenderer<PersonDetailsFormLayout, User> createPersonDetailsRenderer() {
        return new ComponentRenderer<>(PersonDetailsFormLayout::new, PersonDetailsFormLayout::setPerson);
    }

    private static class PersonDetailsFormLayout extends FormLayout {
        RichTextEditor editor = new RichTextEditor();

        public PersonDetailsFormLayout() {
            add(editor);

        }

        public void setPerson(User person) {
            editor.asDelta().setValue(TestView.value);
        }
    }
}
