[Bug] Adding a task while being in focus mode in another window displays the task in the "focus" window
1. Open 2 checkvist windows on the same list
2. Window 1: focus on one root task (shift ->)
3. Window 2: add a root task
Added task is displayed in Window 1.
What is expected?
Task is not a sub-task of task focused, so it shouldn't display.
(It also happens at other levels, but only when added task is sibling of the focused task.)
