When you open a high priority role with policies ('emergency'), the policy engine plays this interruption on already opened roles with lower priority ('multimedia').

But when you close the role that triggers policies, they are not reverted back.

For example:

1. open multimedia
2. open emergency
   1. policy is triggerer: ramp down multimedia
3. close emergency
   1. policy is reverted: ramp up multimedia to it's previous level

This last step isn't done.
