List Item: Inconsistent Height

### Details:
1. Add a new Note
2. Press **Option + CMD + C** to insert a List
3. Delete the space at the right hand side of the List Marker

As a result, the cursor's height will decrease.

- [ ] Ensure the TextAttachment height is stable
- [ ] Drop the trailing space: Handle right padding by means of TextAttachment's bounds

Reproduce the issue in the macOS app by creating a Note, inserting a List with Option + CMD + C, and deleting the space after the marker. Start by locating the list marker's TextAttachment handling. Done means the cursor height remains stable and the trailing space is removed while right padding is preserved through the attachment bounds.
