The minecraft:destruction_particles component’s particle_count property does not properly vary across permutation definitions of a custom block.

Demonstration

The attached screenshots demonstrate this issue. Both screenshots showcase a single custom block type. The default permutation (with the obsidian texture) is defined to emit 250 particles on destructoin. Its behavior is correct. The alternative permutation (with the glowstone texture) is defined to emit only 10. Its behavior is incorrect.

Reproduction

The example block shown in the screenshots is as follows:

{
	"format_version": "1.26.20",
	"minecraft:block": {
		"description": {
			"identifier": "bug_particles:custom_block",
			
			"states": {
				"bug_particles:alternative": [false, true]
			}
		},
		
		"components": {
			"minecraft:geometry": "minecraft:geometry.full_block",
			"minecraft:material_instances": {
				"*": {"texture": "obsidian"}
			},
			
			"minecraft:destruction_particles": {"particle_count": 250}
		},
		"permutations": [
			{
				"condition": "q.block_state('bug_particles:alternative')",
				"components": {
					"minecraft:material_instances": {
						"*": {"texture": "glowstone"}
					},
					
					"minecraft:destruction_particles": {"particle_count": 10}
				}
			}
		]
	}
}
