Unable to split List V2 block from middle of list

[dcalhoun]

Description

When the cursor is placed at the end of a list item position in the middle of the list, it is not possibly to split the list block by pressing the Return key twice. This appears to have begun occurring with List V2 blocks enabled using inner blocks.

Step-by-step reproduction instructions

1. Insert a List block with the native editor.
2. Add at least three items to the list.
3. Place the cursor at the end of one of the items in the middle of the list.
4. Press the Return twice.

Expected behaviour

The List block is split in half. The editor contains:

1. A List block with the first half of list items.
2. An empty Paragraph block with cursor focus.
3. A List block with the second half of list items.

Actual behaviour

The editor contains a single List block with an item list item in the middle of the list.
