What exactly should be the correct behavior/interaction ?
Gideon, Champion of Justice - you can't have 2 of them on the battlefield.

Are any other cards possibly affected by this bug ?
-

Confirmed in your savegame.

However, it functions correctly in a clean game (for human player), and in your savegame if you debug 2 into your hand and cast them it will ask for a sacrifice. So maybe it is an AI only issue?

This seems to be same problem of this.So this is fixed or better closed.
