If the window.returnValue property is set to an associative array, the result returned from window.showModalDialog is a blank array. If the returnValue is set to an object, the result is not blank.

Reproducible: Always

Steps to Reproduce:
Page 1:
<button onclick="dumpObject(window.showModalDialog("page2.htm"));">Show Dialog</button>

Page 2:
<button onclick="closeDialog1();">Return [1]</button>
<button onclick="closeDialog2();">Return [2]</button>

closeDialog1 = function()
{
    var result = [];
    result["value"] = "Data returned from dialog";
    window.returnValue = result;
    window.close();
};
closeDialog2 = function()
{
    var result = {};
    result["value"] = "Data returned from dialog";
    window.returnValue = result;
    window.close();
};

Open page 1, show the dialog, click "Return [1]", and note the result. Show the dialog again, click "Return [2]", and note the result.
Actual Results:  
Return [1] returns an empty array. Return [2] returns the expected data.

Expected Results:  
Both methods should return the expected data, as Internet Explorer does.
