Wolves do not get wet when raining in Frozen Oceans

Relates to MC-230678 and MC-238904.

Can confirm.

Can confirm in 1.19.1.

Code analysis (Mojang mappings, 22w42a): In Wolf#tick(), Entity#isInWaterRainOrBubble() is called, which in turn calls Level#isRainingAt(BlockPos). Taking a look at the function:

...
    public boolean isRainingAt(BlockPos $$0) {
        if (!this.isRaining()) {
            return false;
        }
        if (!this.canSeeSky($$0)) {
            return false;
        }
        if (this.getHeightmapPos(Heightmap.Types.MOTION_BLOCKING, $$0).getY() > $$0.getY()) {
            return false;
        }
        Biome $$1 = this.getBiome($$0).value();
        return $$1.getPrecipitation() == Biome.Precipitation.RAIN && $$1.warmEnoughToRain($$0);
    }
...

We can see that the function only returns true if the biome precipitation is RAIN. Frozen oceans have a biome precipitation of SNOW, so this will always be false for frozen oceans. This return statement should probably be changed to something like

return ($$1.getPrecipitation() == Biome.Precipitation.RAIN || $$1.getPrecipitation() == Biome.Precipitation.SNOW) && $$1.warmEnoughToRain($$0);

Edit: I have tested this in 1.19.2 with my extremely limited modding capabilities and verified that this fixes this issue, MC-233893, and MC-247836. I am unsure if it causes other issues, however.

Edit 2: this is now tracked separately at MC-255811.

Appears to be fixed for me in 23w03, most likely due to MC-255811 being fixed. Someone please double check.

Confirmed fixed in 23w03a.
