Incorrect behavior of the list widget (numbered/bulleted) after performing the following actions.

[defcoast]

Steps:

1. Add a list
2. Fill in any text in 2 lines of the list
3. Press Enter
4. Return to the last line of the list with entered text
5. Press Enter several times (e.g. 6 times)
6. Move the cursor to the last line of the list
7. Hold Backspace until the cursor moves to the line of the list with entered text
8. Press Enter twice

Expected result:

Empty lines (added by pressing Enter) are removed
The cursor returns to the line with the filled list item
After pressing Enter twice, a new block starts

Actual result:

The cursor position shifts during the removal of empty lines
Some empty list lines remain
After pressing Enter twice, new empty list lines are added
Even after removing the empty list lines, pressing Enter twice does not start a new block, but instead adds new list lines.
