Altering "Growth Chance" in "sapling behavior" tweaks doesn't change the rate of bonemealing saplings for them to grow.

[GrandeMalum]

I've decided to make saplings grow 4 times slower than in vanilla by setting the value to 0.03125, and I've noticed that the sapling grows with the default vanilla grow speed when using bonemeal on it, which completely nullifies the idea behind the tweak. Is there a way to alter/fix this behavior?

that tweak has the description Chance per update tick at which saplings grow into trees. the config is entirely unrelated to bonemeal.
