Grid mask is shown above Window on Ext.4.1b3

I have an open Ext.window.Window above an Ext.grid.Panel.

Loading the Ext.grid.Panel store adds a loading mask to the grid body as expected, but the mask is shown above the Ext Window.

Didn't happen on b2

Thanks for the report. Her eis my test case, I drag the window over the panel and hit the button in the window to mask the panel and it is above the window.

Code:

---

var panel = new Ext.panel.Panel({
    renderTo : document.body,
    width    : 400,
    height  : 400,
    title    : 'Test'
});

var window = new Ext.window.Window({
    width    : 200,
    height  : 200,
    title    : 'Window',
    autoShow : true,
    items    : [
        {
            xtype  : 'button',
            text    : 'Mask',
            handler : function() {
                panel.setLoading(true);
            }
        }
    ]
});

Hi,

The problem is back again in Ext JS 4.1.1 (GA)

Please check.
