[MC-195015] Item's display name not applying correctly

In minecraft 1.16.1 (Minecraft_server.jar), I have found an issue revolving around display names in items.
If an item's JSON information exceeds a certain length in characters (Not sure which it is), the idem's display name is not applied.

The command used: https://hastebin.com/vohowepeya.makefile
The expected result:

[media]

The actual result:

[media]

There isn't a maximum length for a line of text's JSON information on the tablist, bossbar, action bar, scoreboard and Message Of The Day so I assume that this is unintentional.

Are you pasting the command in chat?

Command for reference:

/give @p diamond_sword{display:{Name:'[{"text":"T","color":"#FF0000","italic":false},{"text":"e","color":"#FF6600"},{"text":"s","color":"#FFCC00"},{"text":"t","color":"#FFFF33"},{"text":"i","color":"#CCCC99"},{"text":"n","color":"#CC6600"},{"text":"g","color":"#CC66CC"},{"text":" ","color":"dark_purple"},{"text":"h","color":"#6699FF"},{"text":"i","color":"#FFCC33"},{"text":"s","color":"#00CC33"},{"text":" ","color":"dark_purple"},{"text":"I","color":"#FFCC99"},{"text":"t","color":"#FF9999"},{"text":"e","color":"#FF99CC"},{"text":"m","color":"#FF66CC"}]'}} 1

No, I am using it in a command block as the command is too long to be used in chat.

Please provide the server log of the time when you tried to run this command.

Update: Trying the example I gave above doesn't cause any more issues, however I managed to re-create with the command below: https://hatebin.com/mkkmhmipym

The console only outputs one message, it being

[16:09:25 INFO]: [@: Gave 1 [Stone] to Klyser8]

Please provide the full server log from the time it started to the moment you are running the command.
