(Firefox :: General, defect)

Description

[shimon doodkin]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0

i textarea that must scroll because it's text is long,
in textarea on undo/redo:
it changes the text (undo/redo)
it moves the caret to the correct place
* it does not scrolls to the caret to show the change;
it selects the changed text on undo from redo;

when i do undo or redo there is no sense to where and what has changed.
i migrated my web file source code editor to firefox and i found core problems(i use Firefox 2)
 and this one of them

Reproducible: Always

Steps to Reproduce:
0. it happened to me in Firefox 2
1. tape many lines long text so you have scrollbars in a textarea 
2. select and delete a word from the end of typed text.
3. scroll to top of textarea
4. click Ctrl+Z once
Actual Results:  
the result: is that it is does not scrolls to the caret.
you see that nothing happened on the screen
but if you will scroll you will find the caret in place
and the added text is corrected in undo and in redo.

Expected Results:  
the expected result: is it will 
remove the added text in step 2,
move the carret,
scroll into view,
also in redo should select the text(not just in undo).

i think it should select the text only if not the whole text is changed in whole text it is not useful.

also misc foo : (not related to the bug);
* it restart the caret position and the scroll position on minor content changes by script like insert tab char near the caret.
* focus on the window takes focus from textarea.
