IOFactory::load failed and the funtion setCommentReference not working

[LinsVert]

Describe the bug and add attachments

When i used IOFactory::load function to load my docx file,throw by:

Argument 3 passed to PhpOffice\PhpWord\Reader\Word2007\AbstractPart::setCommentReference() must be an instance of PhpOffice\PhpWord\Element\AbstractElement, null given, called in vendor/phpoffice/phpword/src/PhpWord/Reader/Word2007/AbstractPart.php on line 337

It should be that the $element in this setCommentReference uses the type specifier,because it works fine in 1.1.0

PS: my file file command tips : Microsoft Word 2007+

Expected behavior

Load word successed

Steps to reproduce

Code:
$word = IOFactory::load($path, $readName);
