When I receive crosswiki notifications, the only place where I can see what they are is the "Recent activity" box. However, this box gets hidden on small screens (both in Vector and in Responsive Monobook). So I can see on my phone that I have notifications, but if I click on them I don't see what they are (if they are from crosswiki). That's clearly not ideal: either merge the crosswiki notifications with the others, or forbid hiding of the selector box, but don't tell me I have messages with no way of telling where they are.

A workaround is to use .mw-echo-ui-notificationsInboxWidget-sidebar {display:block;} in my skin.css file, but that doesn't look great on small screens either. Could the widget box be moved instead of being hidden completely?
Got the same issue here. And worse, the workaround explained above doesn't seem to work for me.
