When I open a new dialog window with the option "modal=yes" (which should be ignored), modifying the dialog window would cause JavaScript errors.

This bug is breaking Gran Paradiso's compatibility with FCKeditor 2.4.x.

Reproducible: Always

Steps to Reproduce:
To reproduce:
1. Open a new, blank window to with window.open() and the option flags "dialog=yes,modal=yes";
2. Set a property within the new window, say with windowObject.myProp = 1.
3. A JavaScript error occurs saying we're setting a property with only a getter.
4. Move the new window around by windowObject.moveTo(x, y).
5. A JavaScript error occurs.
6. Resize the new window by windowObject.resizeTo(width, height).
7. Yet another JavaScript error occurs.
Actual Results:  
Many JavaScript errors

Expected Results:  
The JavaScript errors should not occur unless we're attempting XSS - but we're not.
