343240 - Caret invisible in <textbox> when a <window> has CSS background-color property set to transparent

Status: UNCONFIRMED

(Core :: XUL, defect)

Description

[Hugo]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4
Build Identifier: Mozilla Thunderbird version 1.5.0.4 (20060516)

In an extension development, the blinking cursor doesn't appear in the XUL element textbox when it is in a window with a CSS background-color property set to transparent. I can write a text, but I don't know where I am. The selection of the text has too some strange behavior (the first letter is not selected at the screen, but if I copy the string, the first letter is included...).

Reproducible: Always

Steps to Reproduce:
1. In an extension, in a xul file, create a window:
<window xmlns='http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul' id="transparent-window" style="background-color: transprent;">
...
</window>
2. include a textbox:
<textbox/>
3. open the window: window.open("chrome://tranprent-window/content/tranprent-window.xul","tranprent-window","chrome");

Actual Results:  
textbox has no caret (blinking cursor)

This bug was fixed in FF 1.5 but has reappeared in 2.0.
They know about this...

But when will it be fixed?? 
I'm waiting for so long now...
(and I hate it because I need to use IE now for my apps)

Reporter and others this is Thunderbird or Firefox related bug?

This is not a Thunderbird bug. It's Core - XUL and needs confirmation.
