I saw the Welcome to XF 1.5 notice, with click here for more details. I clicked it and got to the HYS thread. Again I see the Welcome to XF 1.5 notice, click here for more details! Now... Didn't I click that already.... Ok click again, same page! Then I realize oh you have to dismiss it (and the top right cross wasn't visible until I moved my mouse on it).
a> When someone clicks on the link inside the notification, the notification should be auto-dismissed
b> At the very least, the page which the notifications links to (if inside xenforo) should not show the notification.
