On a group layer in the sdk if visibilityMode is set to independent why does it not respect this

[MikeBehan]

On a group layer like below

            new GroupLayer({
              title: 'Example',
              visibilityMode: "independent",
              layers: featureLayers
            }

In the follow screen shot if a user checks the eye of the whole group layer  to hide then go to a sublayer and check that to show nothing happens our users are find this confusing

 

version is 4.29 of the SDK
