This makes for some ambiguity when we have a focused/selected - * item in the list, and the mouse is hovering a completed download (which - * highlights). - * 2) Windows doesn't show focusrings until after the first time that tab is - * pressed (and by then you're focusing the second item in the panel). - * 3) Richlistbox sets -moz-focusring even when we select it with a mouse. - * - * In general, the desired behaviour is to focus the first item after pressing - * tab/down, and show that focus with a ring. 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.
