List item has no bullet after Backspace and Enter again

[hypest]

Expected

The list item created after backspacing on and item and hitting Enter again should have a bullet.

Observed

There's no bullet on the newly (re)created item.

First reported by @mkevins here using the steps described by @marecar3 here (though for a different issue).

Reproduced

0. Using the Gboard virtual keyboard
1. Create a List with 3 items that have content
2. Put the cursor on the beginning of the 3d row
3. Press backspace. The last two items should have joined now.
4. Press enter. The items will be split again but the last item will not have a bullet.
