Currently opening the action drawer causes notification popups to
"expire", causing some unintended behaviour (ex. dismiss alarm/timer).
This commit removes this behaviour, and also fixes notification popup
expiry while the action drawer is open.
Fixes https://invent.kde.org/plasma/plasma-mobile/-/issues/468
This merge request adjust animations in the VolumeOSD and NotificationPopup to bring consistency and to make it feel better when swiping up a notification.
This fixes a bug where other sources dismissing the current popup notification would cause notifications in waiting to be assigned to the popup index of -1. This would cause these remaining notifications height to get set to a very thin strip at the top of the screen and would no longer automatically dismiss. This also fixes a bug where notifications in the popup drawer would become bunched up together at the top.
