$begingroup$ If only the dielectric is twice as large, the overall capacitor might not have changed much at all. Often the dielectric is the minority of the space in the capacitor. Supposing doubling the voltage in this case makes practically no difference in the package size, will the ESR remain the same? $endgroup$ –
