From https://bugzilla.wikimedia.org/show_bug.cgi?id=41830#c1 : "* It renders titles inconsistently. Sometimes the title is a link to the host page, sometimes the title is unlinked and the name of the host page becomes a link (see attachment, the bottom one has a title with no link and the hostpage is linked, the top 2 are the other way around)." See http://bug-attachment.wikimedia.org/attachment.cgi?id=11316
The linking behavior is now consistent on the overlays (1 link) and the All Notifications page (all pages linked), at least for the currently active notification types.
