App from an App-Group showing the App-Group in foreground in Task Manager

eOS: 2.0-alpha.5-t-20240411393143-dev-nio Device: Motorola G100 (XT2125-4)

I have several Apps grouped in folders on my home screen. When i open one of these apps it is starting accordingly. Starting the "Task Manager" (display all open apps - swiping up) leads to showing the previously opened group in the foreground and the Task Manager in the background. This misbehavior appeared with the 2.0 - has not been there on all 1.* versions.
