                                            </li>
                                        </ul>
                                    </li>
                                </ul>
                            </li>
                        </ul>
                    </li>
                </ul>
            </li>
        </ul>
    </li>
</ul>

3. Paste the content in a Paragraph block.
4. Observe that a List block is created and that the "Block cannot be rendered ..." warning is displayed.
5. Tap on the warning message two times until a bottom sheet is displayed.
6. Tap on the "Ungroup block" option.
7. Observe that no action is performed and that the bottom sheet remains open.

Expected behaviour

The ungroup block option should work, or if ungrouping is unavailable, remove the option from the bottom sheet.

Actual behaviour

The ungroup block option is always displayed and doesn't work on specific cases.
