Hi all,

A viewport with only one panel in the center region doesnt render the margins.

Code:
Ext.application({
    name: 'Example',
    launch: function () {
        Ext.create('Ext.container.Viewport', {
            layout: 'border',
            items: [{
                region: 'center',
                title: 'Example',
                html: 'My App',
                margins: '5 5 5 5'
            }]
        });
    }
});
Thanks!

Sieg
