how to disable gjs-hoverable class from elements

hi @artf  
 i am using your boilerplate plugin and i want to disable hoverable property from all the elements as screenshot below yellow area appearing on hover
 i tried to do this 
` const updateAll = model => {
        model.set({hoverable:false});
        model.get('components').each(model => updateAll(model));
    }
    updateAll(editor.DomComponents.getWrapper());
`
It stops hoverable property  only for wrapper.
Can you tell me  how to stop  that property for all the elements  ?
Thanks
