When faster-minecarts is installed and z_combined/furnace_minecart/MixinFurnaceMinecartEntity is eligible
furnace carts tend to bounce between turns

I'll try and replace some of the Overwrites; did it like that just to make things easier initially and because I figured furnace minecarts were basically forgotten and nobody else was patching them.

The bouncing actually happens sometimes with just Fabrication, too.
