Status: RESOLVED WORKSFORME

(Core :: Layout: Form Controls, defect, P2)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3a) Gecko/20021210
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3a) Gecko/20021210

If you use OnFocus on a File Input Form tag, when you click "Browse" nothing
happens, and a second "Browse" button appears right next to the first one. 
Clicking on the original "Browse" button again correctly launches the file
upload dialogue.  Clicking on the magically-appeared new "Browse" button does
nothing.  This has been happening for as long as I can remember (way back to
Moz1.0?? and prior??)

Reproducible: Always

Steps to Reproduce:
1. Using a form such as: <form><input TYPE="file" NAME="filetoupload"
onfocus="this.style.background='#dddddd';"></form>
2. Click the Browse button

Actual Results:  
A second Browse button magically appears next to the original Browse button. 
Clicking on it does nothing, clicking on the original Browse button brings up
the file upload dialogue.

Expected Results:  
Immediately bring up the file upload dialogue.

Confirmed.  Potentially related to bug 176100.  Note that the browse dialog does
not come up.  This only happens when you set style, and possibly only
background; probably something is causing a reframe at the exact moment that we
want to bring up the browse dialog.

The attachment to bug 176100 does not fix this bug.

[John Keiser (jkeiser)]

My concern is more that it was *caused* by the previous attachment in that bug.

Nah, this thing has been around forever (a year plus?), I just finally got
around to reporting it.

Reproduced on Win XP, 12/16 Trunk

Is this still a problem?  The inline style changes in 1.4a should have cleared
this up, and I cannot reproduce the problem in a current build...

Marking so (since I did check the trunk).
