Solo/mute on folder doesn't propagate to tracks from the same link group

When I create a few tracks and assign them to the same link group with the Mute/Solo/Listen checkbox checked, soloing/muting one of them causes the other tracks to become soloed/muted as well. This is the correct and expected behavior in Cubase.

Now when I put one of the tracks into a folder and solo/mute this folder it is only the track within the folder that gets soloed/muted. The other tracks do not react at all. Aren’t they supposed to react to the changed solo state since all of them are part of the same Mute/Solo/Listen link group? Looks like a bug to me.

Also, the solo/mute icons for the same track in the mix console and the arrangement view do not match when the routing is changed, as shown in the screen recording.
