+/**
+ * A few words on focus and focusrings
+ *
+ * We do quite a few hacks in the Downloads Panel for focusrings. In fact, we
+ * basically suppress most if not all XUL-level focusrings, and style/draw
+ * them ourselves (using :focus instead of -moz-focusring). There are a few
+ * reasons for this:
+ *
+ * 1) Richlists on OSX don't have focusrings; instead, they are shown as
+ * selected. 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. If the panel is
+ * closed or the mouse moves over the panel, we remove the attribute.
