Ioninc lab shows Android like UI when in iOS mode!

Hi,
I recently updated the Ionic CLI from 3.20.0 to 4.0.0. Now ionic lab shows Android like UI when in iOS mode! How can I get the components iOS-like when the selected platform is iOS?

This is a known bug. For now, use the Ionic DevApp on your iphone to see your app in ios mode or pass the --platform=ios to ionic serve
