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

To workaround this issue you can incorporate the JavaScript code provided in this example markup:

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