notify-osd needs to announce it does not support actions so that
applications can check the capability presence and adapt their behavior
accordingly. The DX team patched quite a few applications so that they
checked this capability (most patches have been upstreamed IIRC).

Since it was however not possible to patch all applications, it was
decided that if an application ignored notify-osd capabilities and sent
notification with actions anyway, notify-osd would show a message box
with action buttons. This felt less harmful than just ignoring actions.
