Comment (by skithund):

 This is the only ''reliable'' way to fix this, that I can think of.

 {{{
 // Only PHP versions 8.2.17, 8.3.4 and later have reliable image format
 detection
 if ( version_compare( PHP_VERSION, '8.2.17', '>=' ) && ( version_compare(
 PHP_VERSION, '8.3.0', '<' ) || version_compare( PHP_VERSION, '8.3.4', '>='
 ) ) ) {
   return ( $image_types & IMG_AVIF ) !== 0;
 } else {
   return false;
 }
 }}}

 Calling the actual `imageavif()` function to test for AVIF support doesn't
 even return `false`. Returns `true` and "AVIF image support has been
 disabled" warning.

 From [https://www.php.net/manual/en/function.imageavif.php PHP doc]
 > Return Values
 > Returns true on success or false on failure.
 > __**Caution** However, if libgd fails to output the image, this function
 returns true.__
