Unordered list does not work correctly

[zavvla]

Describe the bug
Unordered list does not work correctly.

To Reproduce

1. Open SnappyMail.
2. Create a new letter.
3. Switch to text formatting mode.
4. Write text, for example "list:" and go to a new (empty) line.
5. Click the "unordered list" button.
6. The marker is not set.

Expected behavior
It was expected that a marker would be set, and when moving to a new line, the marker would also be set. If you select text and click "unordered list", a marker will appear at the first line. This behavior is incorrect.
