This bug causes incorrect user behavior. Lists cannot be disconnected with Enter, in some cases user cannot add multiple empty paragraphs. 

For the time being you can resolve the issue by incorporating the following JS code block:

<telerik:RadEditor runat="server" ID="RadEditor1">
</telerik:RadEditor>

<script type="text/javascript">
    var setCursorFn = Telerik.Web.UI.Editor.Utils._setCursorInNode;
    Telerik.Web.UI.Editor.Utils._setCursorInNode = function (cursorElement, container, editor) {
        setCursorFn.call(this, cursorElement, container, editor);
        if ($telerik.isChrome) {
            var selection = editor.getSelection();
            var range = selection.getRange();
            if (!range.collapsed) {
                range.collapse();
                selection.selectRange(range);
            }
        }
    }
</script>
