Bug report

PHPStan is overly eager in determining a call to propery_exists() always returns false in PHP 8.2
when a class does not define a property itself - however its children might define the property.
In case of a final class, the result of property_exists() is indeed fixed.

I believe this change has been introduced due to the deprecation of dynamic properties in PHP 8.2, thus PHPStan
is behaving differently there.

Expected output

No error in the linked snippet, the code works as written (and property_exists() does return different results): https://3v4l.org/3pFPb
