381884 - onfocus event is fired twice on activating the window by clicking the title bar

Status: NEW

(Core :: Widget: Gtk, defect, P5)

Description

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

See the URL:
data:text/html,<script type="text/javascript">var count=0;</script><input value="0" onfocus="this.value=++count;">

This testcase increments the numeric in the editor at onfocus events of the editor.

You set the focus to the editor, and change the active window to another application's window (i.e., deactivate the fx window).

And re-activate the fx window.

The counter should be incremented only once, but on linux it is incremented twice. (trunk/FedoraCore6)

I cannot reproduce this on Win and Mac.

|OnContainerFocusInEvent| is called twice, is this a cause?
# the hex is a pointer to the nsWindow object.

er, this bug happens at activating the window by clicking the title bar of the window. I cannot reproduce it with Alt + Tab or clicking the other points.

I don't seem to be able to reproduce with Firefox 3.5.1 (on Linux).
