I open the mac app and double click on an item. I add a subtask and when I hit return, the subtask is added, but the div that contains the sub task does not grow with the list of items. You have to go back to "today" and then double click on the task again in order to see the complete list of tasks and then add a new one.

what should happen is that when I add a new subtask, the div that contains it should grow to contain all the subtasks and the line for the new subtask.
