Window containing resizable container acting wired.

Hi,

I created a Window containing a container that can be resized, in Ext 4.2 both the window and container could be resized.

In Ext 5 the same example lets you either have a resizer on the window or the Container.

Are there any new configurations that have to be set to get the same result in Next 5 ?

Thanks in advance.
