Configured features that use minecraft:decorated prevent all configured features from loading in custom biomes

When using custom biomes, trying to add a configured feature that includes the minecraft:decorated feature found in the most recent vanilla worldgen files provided by slicedlime causes all configured features for that biome to not load.

EXPECTED: Trees and stuff should appear in the world.

ACTUAL: No configured features appear at all.

Attached is an example data pack that the bug appears in. (Note that the configured feature example:example is an exact copy of trees_birch from the vanilla worldgen files, except for the name.) I've also included a picture of the empty world that appears, instead of one full of trees like there should be. 

EDIT: The launcher log returns this error when attempting to use the data pack:

Feature: No key name in MapLike[\\{"config":{"feature":"minecraft:birch_bees_0002","decorator":{"config":{"outer":{"config":{},"type":"minecraft:square"},"inner":
{"config":{},"type":"minecraft:heightmap"}},"type":"minecraft:decorated"}},"type":"minecraft:decorated"}]

Will I need to create a new issue, or edit this one?

Edit this one, I think

With the current world generation changes in the 1.18 snapshots is this still an issue in 21w40a

This should be marked as Fixed, since the minecraft:decorated feature type was removed in 1.18 pre-release 1.
