scrollTo methods in Grid cause render bugs

[sirbris]

Vaadin 14.2.1:
When adding items to a Grid and programatically scrolling to the end, empty rows appear at the top after 3rd time.
Small test case scenario to reproduce the issue... press button at least three times.

        List<String> items = new ArrayList<>();
        Grid<String> grid = new Grid<>();
        grid.setItems(items);
        grid.addColumn(item -> item);

        Button btn = new Button("Add item");
        btn.addClickListener(event -> {
            items.add("New item " + System.currentTimeMillis());
            grid.getDataProvider().refreshAll();
            grid.scrollToEnd();
        });

        add(grid, btn);

Yes, that workaround worked

Sometimes we experience a similar problem with scrollToIndex in a TreeGrid:

Is it possible that the underlying issue is the same as described here?
