To recreate:
  1. type something in one of the tasks in the task list
  2. Click on + Add
  3. The table creates a row and the text input is focused. However the Task details sidebar also opens.
I often start typing and not see feedback. I only realize that the text is being typed in the table row behind the sidebar. It makes me duplicate information and sometimes delete the task by accident.
Expectation: the text input focuses on the sidebar task name instead of the table row. I also expect that table only creates a new row when I am done with the task sidebar and I save.
