How does the 'Burn After Reading' card work in the app? (2022. 08. taboo)

Signum Crucis (LV 2, XP 0) https://arkhamdb.com/card/07197

Drawing Thin (LV 0, XP 3) https://arkhamdb.com/card/05159

As the target of the 'Burn After Reading' card, if I choose the 'Signum Crucis' card or if I choose the 'Drawing Thin' card, I wonder how the app handles this. (Especially when filling the empty space with cards)

(In the current version, the 'Burn After Reading' card doesn't seem to be able to select a target.)
