User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4

A page with both Arabic and English text in the title causes the window caption and the tab caption to display differently.

In a test case i set up, I wrote

<title>العربية - English</title>

The tab caption displays

العربية - English

while the window caption displays

English - العربية

I am no expert on bidi or unicode, so I am not sure which order is the correct one. However, the inconsistent display is most certainly a bug.

I haven't had a chance to test this outside of my mac, or with other ltr/rtl language combinations.

Reproducible: Always

Steps to Reproduce:
1. Visit a page with Arabic and English in the title
2. Open a new tab or otherwise make tabs visible
3. Observe the difference between the window caption and the tab caption in the Arabic/English tab
Actual Results:  
"العربية - English" in the tab caption, "English - العربية" in the window caption.

Expected Results:  
The same ordering (whichever the correct one is) in both captions.

This is a mass search for bugs which are in the Firefox General component, are
UNCO, have not been changed for 500 days and have an unspecified version. 

Reporter, can you please update to Firefox 3.6.10 or later, create a fresh profile, http://support.mozilla.com/en-US/kb/managing+profiles, and test again. If you still see the issue, please update this bug. If the issue is gone, please set the status to RESOLVED > WORKSFORME.

I believe this is a duplicate of Bug 347502, which was filed against Linux. The general gist of the issues seem to match, and the same overall problem is pointed out in the screenshots.
