Screenshot of the issue

SUMMARY
Thumbnails do not work for DOCX and DOC files (and possibly other Microsoft Office formats like xls files)
STEPS TO REPRODUCE
1.  Create a docx file (you can use the one attached) and put it into a folder in Dolphin.

OBSERVED RESULT
No thumbnail is generated.

EXPECTED RESULT
Thumbnail is generated. For Open Document formats, this already works thanks to a fix for bug https://bugs.kde.org/show_bug.cgi?id=375176

I have kubuntu 25.04, and although odt files have a fine preview, docx files don't. Show in many cases I cannot recognize files if I won't open them in libreoffice. I read a comment by kbroulik, 2y ago saying that"We just extract the embedded Thumbnail.png in the DOCX/XLSX/PPTX. It seems Microsoft Office often doesn’t generate the file so we cannot display it.". So what's the situation now? Actually it is the only frequently used files that I cannot preview.
