PHP speadsheet modifies libxml_disable_entity_loader value

[stephane-de]

This is:

• a bug report

What is the expected behavior?

The value of libxml_disable_entity_loader stay the same after I use PhpSpreadsheet

What is the current behavior?

Since 1.5.1 and #780
The value is changed by :
libxml_disable_entity_loader(true);

What are the steps to reproduce?

(where test.xlsx is any valid xlsx file)

<?php

require __DIR__ . '/vendor/autoload.php';

$previousValue =  libxml_disable_entity_loader(false);
print_r('previous value: '.$previousValue."\n");

// Create new Spreadsheet object
$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
\PhpOffice\PhpSpreadsheet\IOFactory::load('test.xlsx');

// add code that show the issue here...
$newValue =  libxml_disable_entity_loader(false);
print_r('new value: '.$newValue."\n");

With 1.5.1 :
previous value:
new value: 1

With 1.5.0
previous value:
new value:

Which versions of PhpSpreadsheet and PHP are affected?

PhpSpreadsheet 1.5.1
PHP 7.2
