Steps to reproduce:
0. &#x202e; is the RIGHT-TO-LEFT OVERRIDE char (RLO)
1. Write an HTML page with "<title>RTL: &#x202e; Hello there</title>"
2. Open the HTML page and note the title in the tabbar

Actual result:
1. The title in the tabbar does not respect the RLO: the title shown is "RTL: Hello there"

Expected result:
1. The title in the tabbar respects the RLO: the title should display as "RTL: ereht olleH"

Related is a bug in the window title, but I'll write that in a follow-up bug.
