Contenteditable megabug with nested ul/li structure

Reported by: Aleksey Owned by: Piotrek Koszuliński

Component: Core : Editable Version:
Keywords: Cc:

Description

1). Create simple html-document with the following simple structure:

<!DOCTYPE html>

<html>

<head>

<script src="ckeditor/ckeditor.js"></script>

</head>

<body>

<ul>

<li>Section 1

<ul>

<li>

<div contenteditable="true">Sub-section 1.1</div>

</li> <li>

<div contenteditable="true">Sub-section 1.2</div>

</li>

</ul>

</li>

</ul>

</body>

</html>

2). Open page in latest version of Firefox/Google Chrome (not tested others).

3). Click on "Sub-section 1.1" or "Sub-section 1.2" node. CKEditor will be loaded for the appropriate field.

4). Put the caret to the start of the edited node.

5). Press "Backspace" hotkey and you'll see that DOM-model is broken very hard:(((.

Indeed, DOM is broken badly. CKEditor 4.3.3 is already closed, so we'll fix this in 4.3.4.

Problem can be reproduced in all browsers from CKEditor 4.0. It doesn't occur in beta

On first Backspace press text is moved from lower li element to upper one.

On second Backspace press Blink, Webkit and IE act as if Back button (they go to previous page) was pressed while Firefox throws error: Message: TypeError: range is undefined
URI: /ckeditor4/core/editable.js
Line: 592
Code: path = range.startPath()
