Describe the bug No suggestions available for class with ArrayAccess returning object using Square brackets

Describe the eclipse environment Eclipse PDT 8.1.0.202307051059

To Reproduce Steps to reproduce the behavior:

1. Copy this code

   
   #!/usr/bin/php
   <?php

class ArrayNewObject {

public $prop;

public function __construct($prop)
{
    $this->prop = $prop;
}

}

class ArrayNewObjectCollection implements ArrayAccess {

private $members;

/**
 *
 * {@inheritdoc}
 * @see ArrayAccess::offsetGet()
 */
public function offsetGet(mixed $offset): ?ArrayNewObject
{
    if (isset($this->members[$offset])) {
        return $this->members[$offset];
    } else {
        return null;
    }
}

public function offsetExists(mixed $offset): bool
{}

public function offsetUnset(mixed $offset): void
{}

public function offsetSet(mixed $offset, mixed $value): void
{
    $this->members[$offset] = $value;
}

}

$array_new_collection = new ArrayNewObjectCollection(); $array_new_collection['my_key_1'] = new ArrayNewObject('Hello'); $array_new_collection['my_key_2'] = new ArrayNewObject('World');

echo 'Short array access: ' . $array_new_collection['my_key_1']->prop . " " . $array_new_collection['my_key_2']->prop . PHP_EOL; echo 'Method array access: ' . $array_new_collection->offsetGet('my_key_1')->prop . " " . $array_new_collection->offsetGet('my_key_2')->prop . PHP_EOL;

//$array_new_collection['my_key_1']->

2. Uncomment last line with "$array_new_collection['my_key_1']->"
3. Ctrl + Space at the end of this line
4. Search for "prop" property

**Expected behavior**
Suggestion: $array_new_collection['my_key_1']->prop

For now PDT not always understand arrayaccess interface. Marking as an enhancement.
