205936 - Strange editing artefacts

Status: NEW

(Core :: DOM: Editor, defect, P5)

Description

[[e-mail]]

Feel free to split this up into separate bugs; I'm not sure what's what.
Steps to reproduce problem:
1. Open a new editor window
2. Change the paragraph type to preformat
3. Type 1<cr>2<cr>3<cr>4<cr>
4. Change the paragraph type to body
5. Type 5<cr>6<cr>7<cr>8<cr>
At this point I would expect to see a blank line betwee 4 and 5, and the rest of
the bug can't be duplicated without it, so to force it to appear:
6. Select All, Delete, Undo
Now we have 1-4 (monospace), blank line, 5-8 (proportional)
7. Place the cursor before the 7, and shift+up 4 times.
8. Press Delete
Now we have two blank lines between 2 and 7...
9. Press Up, Right, Delete
Actual results: 7 gets deleted !!!
10. Undo, Right, Left, Delete
This seems to work, but generates 3 assertions :-/
11. Undo, Right, Backspace, Undo, Undo
Now the nodes are all messed up :-( dataloss?

Bulk-downgrade of unassigned, >=5 years untouched DOM/Storage bugs' priority.

If you have reason to believe this is wrong (especially for the severity), please write a comment and ni :jstutte.
