Take the example below , The props data pretend to be part of the 'data' of every component , i assume this because you can access the props data using this.property_name, like the normal scope data AND the props will update in every change of the variable even the VueDevtools will update to the new value , but the DOM will not render the changes, i guess this happen because the props are not $watched properties , and the solution that i found is assign the props to a real $watched data property in the mounted method
