[MCPE-186255] Some flattened IDs are still incorrectly overwritten by original ID in blocks.json with format

A "format_version" field was introduced in 1.21.20 for the blocks.json file. This controls how IDs which were flattened, but remained IDs for a single block, are treated. For example, sponge no longer controls wet_sponge as of format_version 1.21.30.

Two blocks still do not work correctly: dirt and its flattened ID, coarse_dirt. In addition, sandstone and red_sandstone only work when the entries are in a specific order.

For example, the following configuration (from the attached sample pack) should cause dirt and coarse_dirt to do different things:

Dirt: Random texture rotation, sculk sounds

Coarse Dirt: No rotation, bamboo sounds

This does not have the intended result in-game. Coarse dirt still rotates and makes sculk sounds:

Blocks which were flattened and retained their original ID as a single ID can be affected by this problem, but only some IDs are affected. Here is a table:

Original ID	Flattened IDs	Flattened IDs Apply Separate Properties
dirt	dirt coarse_dirt	❌(Never works when both IDs are present, regardless of ID order in blocks.json.)
stone	stone andesite polished_andesite granite polished_granite diorite polished_diorite	✅
prismarine	prismarine prismarine_bricks dark_prismarine	✅
quartz_block	quartz_block chiseled_quartz_block quartz_pillar smooth_quartz	✅
sponge	sponge wet_sponge	✅
anvil	anvil chipped_anvil damaged_anvil deprecated_anvil	✅
purpur_block	purpur_block purpur_pillar deprecated_purpur_block_1 deprecated_purpur_block_2	✅
sand	sand red_sand	✅
sandstone	sandstone chiseled_sandstone cut_sandstone smooth_sandstone	❌ (Only works if new ID is placed after original ID in blocks.json. The opposite order fails.)
red_sandstone	red_sandstone chiseled_red_sandstone cut_red_sandstone smooth_red_sandstone	❌ (Only works if new ID is placed after original ID in blocks.json. The opposite order fails.)
cobblestone_wall	cobblestone_wall mossy_cobblestone_wall granite_wall diorite_wall andesite_wall sandstone_wall brick_wall stone_brick_wall mossy_stone_brick_wall nether_brick_wall end_stone_brick_wall prismarine_wall red_sandstone_wall red_nether_brick_wall	✅

Expected Result

When blocks.json format_version is set to 1.21.20 or higher, properties assigned to dirt in will NOT be applied to coarse_dirt, which is a separate block ID as of 1.21.20. Sandstone IDs should do this as well.

Observed Result

In blocks.json with 1.21.20+ format_versions, coarse_dirt properties are still overwritten by dirt, making it impossible to modify properties of both blocks at the same time. sandstone and red_sandstone IDs overwrite properties set earlier in the file for all sandstone variants.
