PEAR.WhiteSpace.ObjectOperatorIndent can't choose expected indentation

[lucassabreu]

Describe the bug
The rule PEAR.WhiteSpace.ObjectOperatorIndent always shows an error for indentation space for object operator when on a array that has a embedded array before it.

If i move the key brand from the code sample to the end of the array the error is not reported anymore.

Code sample

<?php

namespace Example;

class Bug
{
    public function toJson(array $list): array
    {
        return [
            'brand' => [
                'id' => $item->product()->brand()->id(),
                'title' => $item->product()->brand()->name(),
            ],
            'charges' => $item->charges()
                ->toArray(), // Object operator not indented correctly; expected 20 spaces but found 16
        ];
    }
}

Expected behavior
PHPCS and PHPCPF should be able to "select" the right indentation when on a array, even if a "embedded array" before it.

Versions (please complete the following information):

• OS: Linux
• PHP: 7.4
• PHPCS: 3.5.0, 3.7.1
• Standard: see "Custom ruleset"
