[orca-list] Accessibility in Plasmas new notification system, QAccessible doesnt provide "NOTIFICATION"

[Joanmarie Diggs]

Hey Chrys, Frederik.

Related question: Where are the mappings from QAccessible::Role to
ATK/AT-SPI2 roles? For instance, there's no such role as HelpBalloon in
ATK/AT-SPI2. So if that gets used, what is exposed to Orca for the role?
