Commands with items in containers aren't converted to item components

[LaserSlime]

If there is a command that places a hopper with items in it for example, the items won't be converted to the item component format.

I noticed this with this command:
/setblock -39 30 707 minecraft:hopper[enabled=true,facing=east]{Items:[{Count:41b,Slot:0b,id:"minecraft:blue_dye",tag:{display:{Lore:['[{"text":"- gɾɑпɫs ɫhɛ gɪƒɫ oƒ ᴜпժɛɾɯɑɫɛɾ","italic":true,"color":"gray"}]','[{"text":"ɾɛsρɪɾɑɫɪoп oпcɛ gɪνɛп ɫo ɫhɛ shɾɪпɛ","italic":true,"color":"gray"}]','[{"text":"ƅɛhɪпժ ɫhɛ ɛпժlɛss ɫᴜппɛl.","italic":true,"color":"gray"}]'],Name:'[{"text":"🌊","italic":false,"color":"aqua"},{"text":" "},{"text":"Λզ","bold":true},{"text":"ᴜɑ","bold":true,"color":"dark_aqua"},{"text":" ","bold":true},{"text":"Δᴜ","bold":true,"color":"blue"},{"text":"sɫ","bold":true,"color":"dark_blue"},{"text":" ","bold":false,"color":"dark_blue"},{"text":"🌊","bold":false,"color":"dark_blue"}]'}}},{Count:1b,Slot:1b,id:"minecraft:blue_dye",tag:{display:{Lore:['[{"text":"- gɾɑпɫs ɫhɛ gɪƒɫ oƒ ᴜпժɛɾɯɑɫɛɾ","italic":true,"color":"gray"}]','[{"text":"ɾɛsρɪɾɑɫɪoп oпcɛ gɪνɛп ɫo ɫhɛ shɾɪпɛ","italic":true,"color":"gray"}]','[{"text":"ƅɛhɪпժ ɫhɛ ɛпժlɛss ɫᴜппɛl.","italic":true,"color":"gray"}]'],Name:'[{"text":"🌊","italic":false,"color":"aqua"},{"text":" "},{"text":"Λզ","bold":true},{"text":"ᴜɑ","bold":true,"color":"dark_aqua"},{"text":" ","bold":true},{"text":"Δᴜ","bold":true,"color":"blue"},{"text":"sɫ","bold":true,"color":"dark_blue"},{"text":" ","bold":false,"color":"dark_blue"},{"text":"🌊","bold":false,"color":"dark_blue"}]'}}},{Count:1b,Slot:2b,id:"minecraft:blue_dye",tag:{display:{Lore:['[{"text":"- gɾɑпɫs ɫhɛ gɪƒɫ oƒ ᴜпժɛɾɯɑɫɛɾ","italic":true,"color":"gray"}]','[{"text":"ɾɛsρɪɾɑɫɪoп oпcɛ gɪνɛп ɫo ɫhɛ shɾɪпɛ","italic":true,"color":"gray"}]','[{"text":"ƅɛhɪпժ ɫhɛ ɛпժlɛss ɫᴜппɛl.","italic":true,"color":"gray"}]'],Name:'[{"text":"🌊","italic":false,"color":"aqua"},{"text":" "},{"text":"Λզ","bold":true},{"text":"ᴜɑ","bold":true,"color":"dark_aqua"},{"text":" ","bold":true},{"text":"Δᴜ","bold":true,"color":"blue"},{"text":"sɫ","bold":true,"color":"dark_blue"},{"text":" ","bold":false,"color":"dark_blue"},{"text":"🌊","bold":false,"color":"dark_blue"}]'}}},{Count:1b,Slot:3b,id:"minecraft:blue_dye",tag:{display:{Lore:['[{"text":"- gɾɑпɫs ɫhɛ gɪƒɫ oƒ ᴜпժɛɾɯɑɫɛɾ","italic":true,"color":"gray"}]','[{"text":"ɾɛsρɪɾɑɫɪoп oпcɛ gɪνɛп ɫo ɫhɛ shɾɪпɛ","italic":true,"color":"gray"}]','[{"text":"ƅɛhɪпժ ɫhɛ ɛпժlɛss ɫᴜппɛl.","italic":true,"color":"gray"}]'],Name:'[{"text":"🌊","italic":false,"color":"aqua"},{"text":" "},{"text":"Λզ","bold":true},{"text":"ᴜɑ","bold":true,"color":"dark_aqua"},{"text":" ","bold":true},{"text":"Δᴜ","bold":true,"color":"blue"},{"text":"sɫ","bold":true,"color":"dark_blue"},{"text":" ","bold":false,"color":"dark_blue"},{"text":"🌊","bold":false,"color":"dark_blue"}]'}}},{Count:1b,Slot:4b,id:"minecraft:blue_dye",tag:{display:{Lore:['[{"text":"- gɾɑпɫs ɫhɛ gɪƒɫ oƒ ᴜпժɛɾɯɑɫɛɾ","italic":true,"color":"gray"}]','[{"text":"ɾɛsρɪɾɑɫɪoп oпcɛ gɪνɛп ɫo ɫhɛ shɾɪпɛ","italic":true,"color":"gray"}]','[{"text":"ƅɛhɪпժ ɫhɛ ɛпժlɛss ɫᴜппɛl.","italic":true,"color":"gray"}]'],Name:'[{"text":"🌊","italic":false,"color":"aqua"},{"text":" "},{"text":"Λզ","bold":true},{"text":"ᴜɑ","bold":true,"color":"dark_aqua"},{"text":" ","bold":true},{"text":"Δᴜ","bold":true,"color":"blue"},{"text":"sɫ","bold":true,"color":"dark_blue"},{"text":" ","bold":false,"color":"dark_blue"},{"text":"🌊","bold":false,"color":"dark_blue"}]'}}}],TransferCooldown:0}

As you can see, this command stays the same when using the online converter. The same also goes for being converted in a world.
