Notification of the taskbar, point to open, how to tap disappear?

Testing found that by sending the taskbar notification, tap, or that prompt, and other notifications, tap no.
Tap on how to deal with in order to disappear? Because the task bar notification is to look at it. Too many words can not seem to wrap?

Thank you @ tantahe, I try.
There is a question to ask, then send multiple notifications are displayed in the task bar to scroll when there is no way to get behind the notice appearing in front of notification no. For example: two notifications, the first notification is 9:30, ready to break, the second notification is 10:00 to the rest of the. If you do not see these two prior notice, can not let it show only the second notification: 10:00 to the rest of the. Looks as if the first did not send the same notification.
