Created attachment 142504 [details] from where the cursor is the notification list cannot be scrolled with touchpad. SUMMARY touchpad scrolling not working when cursor is over notification's body in notifications' history tray applet - scrolling is only possible if cursor is either on notification header, on the side or in empty space between notifications. STEPS TO REPRODUCE 1. Make sure there are enough notifications for scrolling to be activated 2. try scrolling while on one of the notification's body 3. then try scrolling on side/on notification's header/between notifications. OBSERVED RESULT Notification cannot be scrolled with touchpad if cursor is over notification's body. EXPECTED RESULT Notification list should be scrolled even if cursor is over notification's body.

Created attachment 142505 [details] from here the list can be scrolled with touchpad. either from here, notification header or scrollbar notification list can be scrolled with touchpad.
Confirmed. Probably the applet's scrollview and the scrollviews in each notification compete with each other.
