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
        ];
    }
}

Custom ruleset

<?xml version="1.0"?>
<ruleset name="My Custom Standard">
    <rule ref="PEAR.WhiteSpace.ObjectOperatorIndent" />
</ruleset>

To reproduce Steps to reproduce the behavior:

1. Create a file called test.php with the code sample above...
2. Run phpcs test.php ...
3. See error message displayed

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"
