This compiles and make us match Chrome Canary 127 and Firefox Nightly 128:

// We should clone all the children of the list item for indenting purposes. However, in case the current
    // selection does not encompass all its children, we need to explicitally handle the same. The original
    // list item too would require proper deletion in that case.
    if (end.anchorNode() == selectedListItem.get() || end.anchorNode()->isDescendantOf(selectedListItem->lastChild()))
        moveParagraphWithClones(start, end, newList.get(), selectedListItem.get());
    else {
        moveParagraphWithClones(start, positionAfterNode(selectedListItem->lastChild()), newList.get(), selectedListItem.get());
        removeNode(*selectedListItem);
    }
