We don't show an error message in this case, just an
empty popup, so that should be fixed regardless.

Allow for the widget to have a mark-as-read button to its individual
groups, as well as change the event listening from 'remove' to 'discard'
The problem with 'remove' event is that it is triggered when an item
is either intentionally removed from the list *and* when an item is
changing its position in the list (move event includes 'remove' and
then 'add' event)
If we listen to 'remove' events we will get both cases, which is
unhelpful. Instead, a new event - 'discard' - was introduced so
we are certain it is used with the clear intention of removing the
item completely.

We have to make sure that any notifications wrapper has the css
term overflow-y: auto; so that the popup menus behave properly.
