Sigh, you moved it from some reason. My proposed diff added
"stack_order" here between "replace" and "transition" to follow
the alphabetical order.

After fixing the alphabetical order:

I could fix the ordering when pushing the patch.

OK, I use this order just according to the order added to this 
test case. Didn't consider the alphabetical order.

If necessary, I can resent a V3 patch.

Best Regards.
