Status: RESOLVED DUPLICATE of bug 1877513

(Core :: DOM: Editor, defect, P3)

User-Agent:       Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:1.5a) Gecko/20030623

Attempting to delete a blank line at the top of a document deletes the following
block tag too.

Reproducible: Always

Steps to Reproduce:
1. Paste the following into the first line of BODY of a blank page (or type the
equivalent in to Composer or Mail Compose window):
-----------------
<br>
<h1>THIS IS HEADER 1</h1>
this is body text<br>
-----------------
2. Move your caret to the beginning of the first line, press DELETE.
3. Also try: UNDO, move caret to beginning of second line, press BACKSPACE

Actual Results:  
The entire H1 style is deleted, not just the blank line, with a single press of
DELETE or BACKSPACE.

Expected Results:  
Only the blank line above the H1 should be deleted.

I can find NO WAY to delete JUST the blank line without going into HTML SOURCE
view.   

Both Composer and Mail Compose window are affected.  This behavior started
sometime after Mozilla 1.3.1.

I think the severity of this bug should be raised. This bug is highly visible
when replying to a mail using the HTML editor.

When replying to a mail, the first line of the edit area contains "John Doe
wrote:". The second line contains the first line of the mail from John Doe with
the blue quote line on the left.

Often I want to remove the "John Doe wrote:" line so that the first line of my
email is the quotation of John Doe's mail. However, this is not possible due to
this bug.

A workaround is to copy everything except the first line to the clipboard, clear
the whole mail and then paste the contents of the clipboard back into the mail.

The backspace behavior is correct.  The forward delete behavior is wrong.
