Not sure if this is the same issue or two separate issues, feel free to split this up.
I posted a new section in Template_talk namespace in hewiki. Then, I got a notification for a mention. I went to the page directly (it was actually already open, so I just refreshed it) and answered; a few minutes later, I received another notification for a mention for the same page, and did the same (refresh + answer)
At no point did I click the notifications themselves, but I did go to the page that they link to. I believe this should mark them as read?
Second issue - both of those notifications, received a few minutes apart, are displayed separately and not bundled. Shouldn't they be bundled, either in a single bundle-notification or in an expandable bundle? The text of the notification is exactly the same, the only difference is the excerpt at the bottom.
