2.81 version ignore light doesn't work

[sjs262]

In the 2.81 version, the modification for spawners to ignore light doesn't work. You can successfully modify the spawners with soul lanterns with/without quartz, and that results in spawners with/without the modification, but the modification essentially doesn't change anything about the spawning. It only spawns in the dark.

I assume since there was nothing about the modification in the changelog, it is the same way in the 2.82 version.
