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.__
