+Popover on disabled components
+------------------------------
+
+It is not possible to use a popover on a disabled component.
+This is because there are no pointer events on disabled components and so events like hover won't fire.
+If you need a popover on a disabled component wrap the component in something like a ``FlowPanel`` or ``LinearPanel``
+and add the popover to the container instead.
