The transparent iframe testcase example shows that transparent iframes in xul
work in mozilla unless opened in chrome windows via the -chrome commandline

Reproducible: Always

Steps to Reproduce:
Set up testcase:

1.  Download the tescase files in testapp.zip and unzip to the c:\ directory

2.  Set up as chrome by adding the following line to
<firefox-home>/chrome/installed-chome.txt:
content,install,url,file:///C:/testapp/chrome/content/testapp/

To see the correct results:

1.  Launch Mozilla 

2.  Enter URL chrome://testapp/content/

To see it broken:

1.  Enter from commandline:

firefox.exe -chrome chrome://testapp/content/




Actual Results:  
iframes in the chrome window are behaving differently than those in the regular
browser window, specifically in this case, the transparent iframe functionality
is broken

Expected Results:  
behavior should be identical (ie. the transparent iframes should work)


A test case is attached.  It can be used to see the behavior in mozilla as a
chrome as well as xulrunner as an application (where it also is broken)

Probably because we don't hook up content viewmanagers to chrome.
