Visiting a new topic page in mediawiki/metawiki doesn't mark the notification as read most of the time while testwiki/test2wiki work in all my tests. This turns out to be a database replication delay, fetching new title from slave in the same request is very likely to fail, testwiki/test2wiki covers the issue with a delay in network request to extension1 db. I couldn't test this in beta labs which is set up with replication delay, it seemed to have some problems.

We have introduced an Echo bug during Spring F. The 'More' link at the bottom of all notification page only shows during initial page load, that means users couldn't view older notifications. I have submitted a patch to fix this: https://gerrit.wikimedia.org/r/#/c/156445/. If possible, we should deploy this fix during swat window before it hits enwiki and all other wikis
