1. select filter "All Tasks" select a random task
2. change the follow up date and then the due date (or vice versa)
--> the focus on the filter "All Tasks" is lost and the first filter "My Tasks" will be selected
--> this also happens when you change the follow up date or the due date two times
--> in some situations this happens also when you set or change the follow up date or due date the first time
