Seems to still be present in [Full 0.8.11 Ending Arc I] which is what seems to be current on Itch.

Similar issue on the Heart outside the atelier, Luccia disappears for a cutscene and doesn’t come back. From that one you CAN menu out. In the Graveyard you’re fully glitched. Additionally, for the one in the Factory, that has the Hundswolf graphics even though it is a Vivi heart.
