Do Not Disturb will lock doors with research inside. Toggling draft/undraft of a researcher seems to not allow the research bench to be seen as an available spot too soon after an unforbid. Since research cannot be prioritize (the only task like this in the game...), Do Not Disturb can cause a loop where research in a specific room with a healing, rescued pawn is impossible.
Perhaps have a simple 'do not forbid this door' flag for Do Not Disturb?
