The Bug
For some reason, when I set the random tick speed, fire behaves like nothing changed.
Steps to Reproduce
Summon a large number of leaves and ensure that the "randomTickSpeed" gamerule is set to its default value, (3).
/fill ~3 ~ ~3 ~10 ~4 ~10 minecraft:oak_leaves[persistent=true] /gamerule randomTickSpeed 3Ignite the leaves, wait around thirty seconds, and take note of how fast the fire spread.
Once again, summon a large number of leaves, but this time, change the "randomTickSpeed" gamerule to a high value in an attempt to increase the speed of the fire spreading.
/fill ~-3 ~ ~-3 ~-10 ~4 ~-10 minecraft:oak_leaves[persistent=true] /gamerule randomTickSpeed 300Wait around thirty seconds and take note of how fast the fire spread.
Take note as to whether or not the "randomTickSpeed" gamerule affects the speed at which fire spreads.
Observed Behavior
The "randomTickSpeed" gamerule no longer affects the speed at which fire spreads.
Expected Behavior
The "randomTickSpeed" gamerule would affect the speed at which fire spreads, just like how it did in past versions of the game (1.12.2).

I wonder why this hasn't been fixed yet.

In 1.12.2 it affected fire spread. But I don't know when it was changed.

Can confirm in 1.18.1.
This is happening because the randomTick() method isn't present anywhere within the FireBlock.java class, therefore making fire spread unaffected by the randomTickSpeed gamerule.
