Severe Lag In Part Editor With DangIt! Continued (1.12.3, modded)

[BadModder54]

Title describes issue. Whenever a part (such as the Mk1 Command Module) that contains the DangIt! resource "Spare Parts" is in the scene, the framerate in the VAB (not in flight, as far as I've observed) drops in linear fashion with the amount of the culprit parts. I checked the Github repository for the mod and it's apparently been an open issue since 2021. Any help on how to fix this would be greatly appreciated, as it could help others enjoy this great mod. The logs from my last session are below, hope this can be resolved!
