Are the magic mirror facial settings supposed to work in real-time?

I would assume this is entirely a Unity system the developers have no control over. What I was wondering (to see if this is a bug or not), are adjusting the various facial features while using the magic mirror, supposed to be showing in real-time as you slide the various sliders?

Currently, the various facial sliders will not show any changes until you move a slider and then let go of the slider with a mouse. Then the facial changes will appear on the character.

I was just wondering if this is working correctly, and if this is known to the team. It is not currently listed in the Known Issues (if this is an issue).

Thanks!

 

They used to... I noted this on the playthrough I started near the end of R73.
