Normal text between obfuscated text can flicker as well

The bug

When text is formatted with obfuscated text, normal text also appears to flash sometimes with random characters. It is flickering between normal and random characters.

How to reproduce

/title @a title [{"text":"@","obfuscated":true},{"text":" Test ","obfuscated":false},{"text":"@","obfuscated":true}]
/title @a title [{"text":"A","obfuscated":true},{"text":" Test ","obfuscated":false},{"text":"A","obfuscated":true}]

Note: It appears to stop happening for a certain character width after a while. So cycling through different widths of characters will cause it to keep appearing.

Cause

This issue could potentially have been produced by the fix to MC-133260.

Obfuscated text is now using every possible Unicode character to cycle through. So perhaps it is choosing characters that also need other characters after them to work correctly (like accent characters) and it is messing up the interpretation of the rest of the text?
