Pillagers are spawning in patrols during the day when the wiki says they shouldn't be.

See https://www.minecraft.net/en-us/article/minecraft-java-edition-1-14-3:
Patrols no longer spawns if the block light level disallows monster spawning
Note that sky light level is not relevant here.
This works as intended, patrols can spawn in daylight if you are on normal or hard difficulty.
