Hey Char69420,
I've tested this and can partially confirm your findings. Wolves do get filtered out correctly by the "Filter neutral" setting, but squids and glow squids are indeed broken:
It seems like Minecraft no longer considers (glow)squids to be a kind of WaterCreatureEntity and instead they have added a new WaterAnimalEntity category which also includes dolphins. (I assume this means the filter is also broken for dolphins.)
With all the testing tools we have now, I wonder if I could set up a unit test for every mob type that these filters are supposed to include/exclude. Should prevent this kind of issue in the future and might even unearth some other filters that are broken in the current version. 🤔
