late-static-bindings is usually worked wonderful for me, bug when I try to find a property is defined by parent-class or child-class, I find it could not check the property is defined by self-class or static-class;


Test script:
---------------
<?php

class app {

    static protected $set = [];

    static public function add($key)
    {
        var_dump(static::$set === self::$set);        
        static::$set[] = $key;
        var_dump(self::$set);
    }

    static public function get()
    {
        return static::$set;
    }
}

class app2 extends app {
    static protected $set = [];
}

class app3 extends app {
    static protected $set = [];    
}


app2::add("app2");

var_dump(app3::get());

Expected result:
----------------
bool(false)
array(0) {
}
array(0) {
}

Actual result:
--------------
bool(true)
array(0) {
}
array(0) {
}
