What happened?

I cannot add a new list between the 2 already existing lists with the Enter button.

Steps to reproduce the problem

1. Add 2 lists with checkboxes
2. Remove space between them
3. Go to the last item of the 1st list and press Enter
4. Press Enter again

Actual result: new checkboxes (list items) created. Expected result: after the second click, the empty list item disappears and it is possible to add the content outside the list.
