/**
 * Description: {@link ControlEditor} editors are not drawn.
 * Steps to reproduce:
 * <ol>
 * <li>Run the snippet.</li>
 * <li>Scroll horizontally so that the first column is no longer visible.</li>
 * </ol>
 * Expected results: The combo editor in the first row and first column, and
 *                   the text editor in the first row and second column,
 *                   are visible and can be interacted with.
 * Actual results: The two editors are not visible but can be interacted with.
