Deleting a bullet point creates another superfluous bullet point

[fbruetting]

Description

When you delete a bullet point of the first level, another first level pullet point gets created to a second(!) level item – which then has two bullet points on both levels.

• Can you reproduce the issue?

Steps to reproduce

1. Make two bullet points of the first level and then one at the second level like in the following image.
   

2. Delete the text of the first bullet point
   

3. With the cursor still at the (empty) first bullet point, now press Delete (not Backspace!). The second-level bullet point now has two bullets.
   

Expected behavior:

No doubled bullet points.

Actual behavior:

Doubled bullet points.
