When you write an obfuscated text component with the same repeated character in a command that supports it, you will notice that the characters are completely synchronized, which is not how it used to be.
Steps to reproduce:
Execute the following commands
/tellraw @s {"text":"!!!!!","obfuscated":true}
/title @s title {"text":"aaaaa","obfuscated":true}
