Description:
------------
This behavior is wether right or wrong ; let's debate :




Test script:
---------------
class A {
	private static $foo = 'Afoo';
	function foo() { return static::$foo; }
}

class B extends A { }


$b = new B;
echo $b->foo();

Expected result:
----------------
PHP <= 7.3 shows :

Fatal error: Uncaught Error: Cannot access  property B::$foo in XXXX

PHP-master shows :

the string 'Afoo'

Actual result:
--------------
What should be the right behavior ?

Considering that the same use-case using non-static attribute, and non static classic $this accesses
the attributes just all right in all PHP versions


Should private static attributes be inherited, or not ?
