180767 - Javascript highlights characters typed into a form textbox, so that only one can be entered

Status: VERIFIED DUPLICATE of bug 178520

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Todd]

User-Agent:       Mozilla/4.78 (Macintosh; U; PPC)
Build Identifier: Mozilla 1.2beta, Build ID 2002101612

In the example page, http://www.mobile.att.net/messagecenter/, the Javascript
causes characters that a user types into the "from" box to be selected
(highlighted) immediately after the key is typed.  Because of this, each
character typed replaces whichever one was typed before it, and only one
character can be entered into the box by a human.  The only workaround is to
paste text from the clipboard.

Reproducible: Always

Steps to Reproduce:
1. Go to URL http://www.mobile.att.net/messagecenter/
2. Try to type in the box labeled "from" 

Actual Results:  
Every keypress replaced whatever character was already in the box.

Expected Results:  
The box should accept normal typing while the box is still active with a cursor
in it.  Perhaps the intention is to highlight it when a user first clicks to
place the cursor in the box or upon leaving the box, but it should not happen
while the cursor is still present and active.  In MSIE, the box seems "normal""
it highlights existing text when switching to that form element.

Confirming reported behavior with Mozilla trunk 20021115xx WinNT.
I will attach a reduced testcase below, which consists of this:

    <input type="text" size="25" onKeyUp="this.focus();">

In IE6, we are able to type without any problems into this textbox.
In Moz, if we type slowly, each character overwrites the previous one.

Attachment: Reduced testcase

focusing the textbox should highlight all the text.  Over to keyboard nav, where
this decision was made, iirc....  We already have bugs on this happening for
.focus() from JS.

I will try Chimera / Mozilla for OSX hopefully this evening.
