the same code base as our pveButton
(selectionchange handling, confirm,etc.)
but with a split button (a button with a menu)

since sometimes, we set the text of the console button
('shell' or 'upgrade')
we do not want to override this everytime, but only
when me.text === null
we cannot use applyIf either, because this overwrites only
if the field is undefined, not null
