Ext js stateful grid/panels / customer provider

I'm trien to setup a stateful grid/panel with ext js 7.3.1 modern like this: https://fiddle.sencha.com/#view/editor&fiddle/3cjn

I've added a Customer Provider for debugging but i cant see any read/write of real settings like width or hidden state. When I run it again, it wont save.

Is there something wrong with my settings?
