// Add operation message (if any)
// Note 1: must handle this separately from other the labels
// because this message is in an anonymous content node
// within an hbox which is dynamically bound to a different
// "addon-needs-*" binding based on the operation type.
// Note 2: must check hbox's CSS "display" property with
// getComputedStyle, because the XUL "hidden" attribute
// never changes.
// Note 3: can't just check whether the hbox has anonymous
// child nodes. If (for example) you disable an extension,
// the hbox gets bound to "addon-needs-disable". But if
// you then immediately re-enable the same extension without
// closing the Add-ons window, the hbox is still bound to
// "addon-needs-disable" (and thus still has the anonymous
// content child nodes with the label containing the now-unused
// &toBeDisabled.label text), but the hbox is no longer visible.
