After digging through the Debian bug logs, they have a bug already filed under a similar title whose fix would cover this as well.

I'm not sure if it's still undergoing testing. I can tell you that Nitrokey is referencing it here:

Understood that you're at the same commit level as Debian. I don't understand why they haven't applied that commit either. My thought was that I'd have better luck filing the request in PureOS's tracker rather than Debian's, because this materially affects the use of the Librem Key.
