Describe the bug and add attachments

Hello and thank you for creating and maintaining this library !
I face a problem with docx generated from template using PHPWord : it opens correctly with LibreOffice 7, but is considered corrupted with LibreOffice 24.

🔴 LibreOffice 24 version details :

Version: 24.8.3.2 (X86_64) / LibreOffice Community
Build ID: 48a6bac9e7e268aeb4c3483fcf825c94556d9f92
CPU threads: 20; OS: Windows 11 X86_64 (10.0 build 22631); UI render: Skia/Vulkan; VCL: win
Locale: fr-FR (fr_FR); UI: fr-FR
Calc: CL threaded

✅ LibreOffice 7 version details :

Version: 7.3.7.2 / LibreOffice Community
Build ID: 30(Build:2)
CPU threads: 4; OS: Linux 6.8; UI render: default; VCL: gtk3
Locale: fr-FR (fr_FR.UTF-8); UI: fr-FR

Expected behavior

I expect a docx generated from a template using PHPWord to be properly formatted for LibreOffice >=24.

Steps to reproduce

• create a simple docx template, for example containing only the paragraph Hello ${toto} !
• process this template and set a value for toto : $templateProcessor->setValue('toto', 'titi');
• save processed template as docx and send it in the BinaryFileResponse of your endpoint
• open the downloaded docx with LibreOffice 24 : the file is corrupted, var are not translated (file still contains Hello ${toto} !)
• open the downloaded docx with LibreOffice 7 : the file opens correctly, var are translated (file contains Hello titi !)

I have also noticed that if you open the file with LibreOffice 7, save it, and then open it with LibreOffice 24, the file will display correctly.
LibreOffice 7 seem to fix the file.
If you change the file extension into zip and search for differences between a never opened file and a saved with LibreOffice 7 file, you will notice several changes, particularly in the word/document.xml.
