Up/down cursor in context menu not working correctly

[anasmi]

Hi @sirbris,

I have tried today to reproduce the issue using the demo within the add-on, but I haven't managed so far. My steps were:

• open context-menu
• navigate using arrow key up/down. This way there were no skipping the line occurrences.

Therefore, could you, please, share the demo application which illustrates the problem? Or, if it's not possible, to share gif/picture and describe your actions, that we would be able to reproduce the problem on our side also,

Thanks in advance!

Here's a simple example:

• open context menu on the grid
• press key down

    public class TestBean {
        private String name = "name";
        private String value = "value";
        private boolean folder = false;

        public TestBean(boolean inFolder) {
            folder = inFolder;
        }

        public String getName() {
            return name;
        }

        public void setName(String inName) {
            name = inName;
        }

        public String getValue() {
            return value;
        }

        public void setValue(String inValue) {
            value = inValue;
        }

        public void setFolder(boolean inFolder) {
            folder = inFolder;
        }

        public boolean isFolder() {
            return folder;
        }

    }

    private Grid<TestBean> grid = new Grid<TestBean>(TestBean.class);
    private GridContextMenu<TestBean> contextMenu = new GridContextMenu<>(grid);
    private ArrayList<TestBean> items = new ArrayList<>();

    @Override
    protected void init(VaadinRequest request) {
        final VerticalLayout layout = new VerticalLayout();
        layout.setMargin(true);
        setContent(layout);

        grid.setDataProvider(new ListDataProvider<>(items));
        grid.setWidth("100%");
        grid.setHeight("400px");

        layout.addComponent(grid);

        contextMenu.addContextMenuOpenListener(event -> handleOpen(event));
    }

    private void handleOpen(ContextMenuOpenEvent inEvent) {
        contextMenu.removeItems();
        contextMenu.addItem("test1", event -> System.out.println("clicked 1"));
        contextMenu.addItem("test2", event -> System.out.println("clicked 2"));
        contextMenu.addItem("test3", event -> System.out.println("clicked 3"));
        contextMenu.addItem("test4", event -> System.out.println("clicked 4"));
        contextMenu.addItem("test5", event -> System.out.println("clicked 5"));
    }

Thanks for the example! :)

Just to be sure, what version of Vaadin are you using?

I have tried to run the demo under context-menu itself, and everything works as expected; also it seems that it works alright in 8.1.7, but 8.4.3 produces already the behavior you see. Therefore, it looks like some change in the framework has affected the work of the addon, but it will require more investigation to be sure, of course.

I use the current Vaadin 8.4.3 and also the current ContextMenu 2.1.0
