496393 - Delete and backspace stop working after hitting delete in empty document

Status: RESOLVED DUPLICATE of bug 462188

(Core :: DOM: Editor, defect)

Description

[Steve Kobes]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10
Build Identifier: 

When an editable document is empty, or has only a single <br>, hitting the Delete key puts the editor into a state where subsequent content inserted programmatically cannot be removed with Delete or Backspace, until the user types some text first.

Reproducible: Always

Steps to Reproduce:
1. Open Midas demo (http://www.mozilla.org/editor/midasdemo/).

2. With the cursor inside the (blank) editor, press Delete.

3. Do something, other than typing, that causes content to be inserted.  For example, click the Insert Table button in the toolbar and insert a 2x2 table.  (The issue is not related to tables specifically - products that embed the editor may have many features that add or replace document content.)

4. Press Ctrl+A to select all.

5. Press Delete or Backspace.
Actual Results:  
In step 5, Delete and Backspace have no effect.  Delete and Backspace remain broken until the user types some text.

Expected Results:  
Delete and Backspace should delete the selected content.

Good: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b3pre) Gecko/20090128 Shiretoko/3.1b3pre
Bad: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b3pre) Gecko/20090127 Shiretoko/3.1b3pre

This is probably a dupe of bug 462188.
