Detailed description of a problem

Minecraft-protocol can currently not read item_display player heads when a profile is specified in the metadata.

When spawning this (I copied this as an example from a mineflayer issue):

It can not read the 'children' (passengers) entity metadatas because the profile is present. When stripping all components:profile stuff, minecraft-protocol can correctly read the metadata again. However, I need to get metadata of item_display heads with profiles

Current code

// See that entity_metadata 
  bot._client.on('entity_metadata', (packet) => {
    console.log(`[entity_metadata] Entity: ${packet.entityId}, Metadata:`, packet.metadata || 'MISSING')
  })

// or do this 5 seconds after bot spawn:
const itemDisplays = Object.values(bot.entities).filter(e => e.name === 'item_display')
 itemDisplays.map(display => {
    console.log('\n')
    console.log(getTransformation(display.metadata))
  })

Expected behavior

The protocol should read metadata of item_display entities even when it has a profile component

Additional context

Thanks in advance for help

[SinanAkkoyun]

Must be due to the properties array not being able to parse the Base64 string or something, because:

/summon minecraft:item_display ~ ~ ~ {item:{id:"minecraft:player_head",Count:1,components:{"minecraft:profile":{id:[I;0,0,0,0],properties:[]}}}} ✅ works

Add Back id but Remove properties /summon minecraft:item_display ~ ~ ~ {item:{id:"minecraft:player_head",Count:1,components:{"minecraft:profile":{id:[I;0,0,0,0]}}}} ✅ works

Add Back properties but Remove id /summon minecraft:item_display ~ ~ ~ {item:{id:"minecraft:player_head",Count:1,components:{"minecraft:profile":{properties:[{name:"textures",value:"SAMPLE_BASE64_STRING"}]}}}} ❌ doesn't work

I tried to look into prismarine-nbt, minecraft-data and minecraft-protocol and am clueless, I would appreciate any help ^^
