Details

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7

CTRL+Z creates an invisible control character in empty text fields.  The field has to start out blank on page load.  If the field is not blank to start with, CTRL-Z just performs undo, like it should.

I have tested this on Firefox 1.5.0.7 in both Windows XP and debian linux, with the default theme.  I discovered it while developing a form application and viewing POST data.  Javascript also picks up the character.  The character cannot be deleted with backspace, or selected with the mouse.

Reproducible: Always

Steps to Reproduce:
1. Create a page with a blank text field.
2. Click in the text field or tab to it.
3. Press CTRL+Z.  There is now an invisible character in the field.



Expected Results:  
I would expect CTRL+Z to do nothing if there is nothing to "undo"

Easy test: focus the "bug#:" field at the bottom of this page, Ctrl+Z, click Find, the URL will have an escaped newline in the query.
