Notifications aren't showing up without a page refresh. This is happening for some users but not others, and sometimes with posts, sometimes with comments. Notifications are implemented both in Calypso and for wp-admin (iframed). I see network requests being fired from both when I open the notifications panel.

In Calypso see: https://github.com/Automattic/wp-calypso/blob/trunk/apps/notifications/src/panel/rest-client/index.js#L485
