Selected task position lost after task deletion

Just as a very minor thing in the UI behavior: in the task tree view, when I select a task using the keyboard and then press CTRL-DEL to delete it, the blue bar indicating the selected task correctly moves to a neighbor of the deleted task, but the position is not really "there" - when I use keyboard to move up or down, it turns out that the real position of the selection is first task of the list.

How to reproduce:
1. Use keyboard to move to some task down the task tree view.
2. Press CTRL-DEL to delete it.
3. Observe where the blue selection bar is.
4. Press up arrow, nothing visible happens (because selection is really already on line 1, even though it is not displayed as such)
5. Press down arrow, the selection jumps to line 2.
