[formatter] Infinity formatting the body of arrow function on every run

[marcovmun]

🐞 Describe the Bug

When running mago format one file is changed every run. I made a small example that has this problem. I tested it and has anything to do with the lenght of the result and the function name inside the array_map. If variable is on letter bigger or smaller or the function name one bigger or smaller. It format once and stays the same.

🔄 Steps to Reproduce

1. Add the example code to a file
2. Run mago format
3. Run again
4. Both code blocks change every time

⚙️ Configuration (mago.toml)

# Mago configuration for RemindoTest
# Docs: https://mago.carthage.software/guide/configuration

<?php

{
    public function run(): void

            reset($row) ?: ''
        ), $this->function1('FOOO BARBAR FOOO barbarbar'));

        $result = array_map(
            fn(array $row): string => reset($row) ?: '',
