Happy Ghast with broken AI spawns instead of Ghastling when using /summon command with the minecraft:as_baby tag

Summary:

When using /summon happy_ghast ~~~ ~~ minecraft:as_baby, instead of spawning a Ghastling, it spawns a small (adult size in versions after 1.21.90.25 Preview) Happy Ghast that has No AI and just floats fast into the air when punched.

Expected Result:

Command when executed should summon a Ghastling with functional AI.

Current Outcome:

Command when executed (formerly, during Preview 1.21.90.25) summoned a Happy Ghast at baby size with no functional AI, but now summons a Happy Ghast at adult size with no functional AI.

Steps to Replicate:

• Open any version of Minecraft Bedrock Edition or Preview to this date.

• Create a new world in creative mode and/or with cheats and commands enabled.

• Summon a Happy Ghast as a baby using commands [ /summon happy_ghast ~~~ ~~ minecraft:as_baby ].

Analysis:

Similar to other mobs spawned with the noticably buggy minecraft:as_baby tag, the attributes of the [specifically unborn] Ghastling are applied to the Happy Ghast, yet both the model and the AI are not updated to match the respective state.
