On PHP 8 I got this error: PHP Warning: Trying to access array offset on value of type int in /var/www/html/public/typo3conf/ext/page_speed_insights/Classes/FormEngine/Elements/History.php line 60 The patch fixes this. I haven't got an array in my tests, but an int with `0` and a string with `"0"`, so used the `is_numeric()` check.
