[BUG] Clicking "I'm done adding tasks" doesn't save task currently being added.
1. Click "Add Task"
2. Type text into task text field such as "Run a mile".
3. Click "I'm done adding tasks".
"Run a mile" to be added as a to-do.
No task is added. This behavior mimics hitting Esc, which is unexpected as I typed in a task and clicked "I'm done adding tasks".
Screenshot of why the current result is jarring (imagine having a lot more text / losing a brain dump...):
