Is it even possible to change the dimension of a tabpanel. I tried height and width but it's not working. Any pointers.

```
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
    jcr:primaryType="cq:Dialog"
    height="{Long}600"
    title="Tiles"
    width="{Long}850"
    xtype="tabpanel">
    <items jcr:primaryType="cq:WidgetCollection">

    </items>
</jcr:root>

```

Thanks
