Apply a loadmask to Viewport that also covers floating Components

Question

How can I add a loadmask within the launch method of the Ext.applcation to the viewport that will also covers floating components like windows when get showed?

Currently the mask work but does not cover any opened window.

I found the answer here, the trick is to increase the z-order of the mask:

Ext.getBody().mask().dom.style.zIndex = '99999';

I made a test, it works for me.
