Strange click behavior in the list of Tasks

Have some Tasks.
Open them, one after the other.
The behavior feels strange:
If one Task is already open and you click directly on another, you would expect that it opens. But instead, the already open Task closes. That may be intended, but it feels unpleasant, because you lose the position in the list so that you need to find the other Task, that you want to open, again.

In addition to that, even if no Task is open, it sometimes needs two clicks on a Task to open it.
