Changing assembling machine animation speed (Version 0.11+)

[Holy-Fire]

In my Zlowdown mod, I have reduced the crafting_speed of assembling machines. In version 0.10 this worked without problem. In version 0.11, apparently reducing the crafting speed also reduces the speed of the animation, which is undesired. How do I modify the animation speed back to the correct value?

Notably, for labs, reducing the speed (via the power consumption) reduced the animation speed, which I corrected by modifying on_animation.animation_speed. But apparently there is no such value for assembling machines.
