Browserscope Rich Text fails 0/149 in IE9 if in standards-compliant mode

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Go to http://www.browserscope.org/richtext/test in IE9.
2. Make sure that the compatibility view is NOT enabled.
3. Click the "Run Tests" button.

What is the expected output? What do you see instead?
Tests should work, but they ALL fail (UNSUPPORTED error).
If I enable compatibility mode, test works and returns 97/149

With the release of IE 9.0 RC1, this test is completely broken: all tests 
return SETUP or EXECUTION EXCEPTION (mouseover), if Compatibility View is 
disabled or enabled, respectively.

Update: http://www.browserscope.org/richtext/test ==> ALL tests fail with 
UNSUPPORTED error on IE9, no compatibility mode. Test works when enabling 
Compatibility mode, though.
http://www.browserscope.org/richtext2/test completely fails nomatter what I 
enable (or disable). It seems to give more "accurate" results if I have 
Compatibility mode disabled, but tests seem to fail in the 3rd with a SETUP or 
EXECUTION exception: unspecified error (in most cases).
