+## Environment
+
+| Property | Value |
+| --- | --- |
+| Product | RadEditor for ASP.NET AJAX |
+| Version | 2023.2.606 |
+
+## Description
+
+When using RadEditor with newline mode set to "P" (Paragraph), deleting text can cause an additional CSS class to be inserted into the paragraph. This is a known bug in the Chromium browser.
+
+## Solution
+
+To stop the auto insertion of the CSS class, you can add the following onkeyup code to your RadEditor:
+
+````ASPX
+<script>
+function OnClientLoadEditor(sender, args) {
+    var $ = $telerik.$;
+    sender.attachEventHandler('onkeyup', function (e) {
+
+        if (e.keyCode === 8 || e.keyCode === 46) {
+
+            var range = sender.get_document().getSelection().getRangeAt(0);
+            var endContainer = range.endContainer;
+            var nodeNextSibling = endContainer.nextSibling;
+
+            if (endContainer.parentNode.tagName.toLowerCase() === "span") {
+                $(range.endContainer.parentNode).replaceWith($(endContainer));
+            }
+
+            else if (nodeNextSibling.tagName.toLowerCase() === "span") {
+                $(nodeNextSibling).replaceWith($(nodeNextSibling).contents());
+            }
+        }
+    });
+}
+</script>
+<telerik:RadEditor runat="server" ID="RadEditor1" OnClientLoad="OnClientLoadEditor">
+    <Content>
+        <p>test</p><p>test</p>			
+    </Content>
+</telerik:RadEditor>
+````
+
+This code attaches an onkeyup event handler to the RadEditor. When the backspace or delete key is pressed, it checks if the current selection is within a `<span>` element. If it is, the `<span>` element is replaced with its contents. This effectively removes the additional CSS class inserted by the browser when deleting text.
