Unstable editing with blockquote and formatted text

[Geir Helge Tjøstolvsen-Schmidt]

We're having a problem when using blockquote and formatted text. After we've been writing a couple of paragraphs and starts to edit the text, line breaks are removed where it shouldn't and wrong characters are removed. I'm reporting this in the same bug since it might be just two ways to reproduce the same bug.

Both examples are reproduced in version 2.5.1 and 2.6 with Firefox 2.0.0.13 on Ubuntu and Windows XP. I've not been able to reproduce the bug in IE 6 or 7.

Line breaks that are removed How to reproduce:

1. Click blockquote and select format "formatted"
2. Type

   a
   a
   a
   

3. Hit enter two times creating a paragraph
4. Type

   b
   b
   b
   

5. Hit enter two times creating a paragraph
6. Type

   c
   c
   c
   

7. Hit CTRL+Z, hit enter once and type

   c
   

8. Move the cursor in front of the last b
9. Hit backspace

The last b is placed after the second b, that's good, but at the same time the last c is placed after the second c.

Wrong character deleted

1. Click blockquote and select format "formatted"
2. type "asdf" hit enter two times and type "hjkl"
3. Move the marker at the beginning of the line with "hjkl"
4. Hit backspace two times in order to move "hjkl" on the same line as "asdf"

Result: One hit on backspace removes the empty line, the next removes the "f" and if you continue the whole line with "asdf" will be deleted.

What I'd expected: The string "hjkl" to be moved at the end of "asdf"

Ah, all my line breaks was removed in the report :(

The editor content should look like this before hitting CTRL+Z:
a
a
a

b
b
b

c
c
c


It's important that you use undo and retype the last c before trying to remove the line break between the second and the third b.
