How to mirror the titlebar of an MSI installer?

I'm trying to internationalize an installation package using WiX (Windows Installer XML), but I keep running into a problem with right to left languages (e.g. Arabic and Hebrew).

I've followed the tutorials, specifically the right to left tutorial. Everything appears as it should in right to left except for the titlebar of the Windows Installer dialog windows.

According to every source I've researched, including that tutorial (which is the one suggested to use by WiX on Sourceforge), mirroring the title开发者_C百科bar is currently impossible.

Has anyone successfully mirrored the titlebar of the Windows Installer dialog windows? If so, how did you do it?
