[Oracle - Entwined Realities] Unable to refund keystone allocated with Controlled Metamorphosis

Bug ref: 458,972,128

I got a Controlled Metamorphosis so I do what every PoE player would do: test the interaction with Oracle - Enmtwined Realities (which give a similar effect).
After confirming that the interaction works, I tried to refund the keystone to remove the jewel. To my surprise the game only give a "click confirm" sfx (as if there are allocated passives in its range) and does nothing. I can see the refund cost so it is definitely refund UI.

Workaround: refund some passives and connect the keystone to the rest of the tree. The jewel should now be removable and the branch can be refunded backward afterward.
