(blocking for now per partner request.  but if the patch is looking overly risky then I think we should reconsider blocking on this)

Ben, are you the right person to take a look at this?

Hi, I tried to take a look at this.

I can't reproduce it on master (though I'm not sure what "Zombie Line" is), so it seems it might be unique to v1.0.1

Unfortunately gaia v1.0.1 doesn't start at all for me on any version of gecko I have. I'm trying to get hold of a v1.0.1 Otoro build so I'll have another go tomorrow if someone doesn't get there before me.

Zombie lines is a hosted game,which is a landscape application. When launching it, if there is no network available,it will display the warning screen(screen shot).

In fact,the problem is not only for zombie lines.it may for all landscape apps.

And you can find it in market place.

I just try to repro on 20130304070202 build and see this.
Before this happens I see: The error dialog in the landscape app is at portrait mode.

The second time I try to repro, the error dialog is correctly put to landscape mode.

I guess something is wrong when we request orientation lock in WM.

It's such difficult to repro second time :/

I believe I know what happens.
This should be another regression from 842627.
Bug 842627 delays the openWindow after mozbrowserloadend events, which contains a step to add fullscreen class to #screen element.
When under fullscreen mode, the statusbar and the utility-tray's z-index is demoted to under appWindow.
So it would appear under current active app.

This also explains why opening another app could resolve this bug, because fullscreen-app is constantly remove every time setDisplayedApp is called in WindowManager.

My patch in bug 844990 should fix this already, but it's not uplifted to v1.0.1 yet.

Following is the log I add to check fullscreen-app state in WM.

After quickly clicking close button when error screen, we will fall into a state that WM THINKS IT IS STILL IN 'ZOMBIE LINES' APP BUT WE ARE NOW AT HOMESCREEN APP.
