What you show is not evaluation remembering, the evaluation is a mate in 12, Stockfish remembers that it's a mate in 12, so it's remembering the evaluation correctly.
What you are asking for is "show all moves up to mate in mate positions", this could be done even without having to interact with the position and seems reasonable, maybe someone else can help.
It looks like Houdini caches the PV for tablebase lines. Stockfish GTB does not. One could add this, but I'm not really sure that the effort is worth the trouble -- all you have to do is make the move you're interested in and you'll get the complete PV. Maybe something else will occur to me that would make this simpler, but I can't imagine a solution that doesn't involve significant surgery.

Oh, if it's not something trivial to fix it's perhaps not worth it. Though I'm biased, I'd rather have that time used for ideas about implementing "position learning"
