Then, if the mouse moves over + * the panel, to hide that focus ring; essentially resetting us to the state + * before pressing the key. + * + * We end up capturing the tab/down key events, and preventing their default + * behaviour. We then set a "keyfocus" attribute on the panel, which allows + * us to draw a ring around the currently focused element.
