Cards on stack at end of previous game display as abilities if they appear in opening hand of next game

Self-explanatory. Previous game ended while Sanctum of Stone Fangs' ability was still on the stack, and receiving it in my opening hand the game after displays it incorrectly.

Reproduce the issue by ending a game with Sanctum of Stone Fangs' ability on the stack, then placing the relevant card in the next game's opening hand. Trace how cards left on the stack are represented when the new game starts and how opening-hand cards are displayed. Done means the card appears as a normal card rather than an ability in the next opening hand.
