Using the ScriptAPI, attempting to use the place feature command via runCommand will not succeed.

Steps to reproduce:

• Download the add-on attached
• Launch Preview 1.21.60.24
• Create a new flat world
• Enable the Beta APIs and Upcoming Creator Feature toggle
• You may need to type /reload

Expected Behaviour:

An oak tree will be placed at 16 -60 16.

Actual Behaviour:

An oak tree is not placed at 16 -60 16. Rather a stone and dirt block is placed there instead. This shows that the ScriptAPI can run commands but specifically the place feature command does not. You can verify that if you destroy the blocks and ran `/place feature minecraft:oak_tree_feature 16 -60 16` yourself, it will place the oak tree.
