Steps to reproduce:
1. Create a text document
2. Import an svg image into it
3. Save the file
4. Try to compress the file with zip
The file saved by libreoffice compresses a lot (often more than 50%). This is due to the fact that the svg image in it is saved uncompressed by libreoffice. This can be checked with zipinfo: the svg image is stored, not deflated.
However, SVG is uncompressed XML. Often HUGE. Meant to be compressed. From wikipedia: "SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted, and, if need be, compressed."
The opendocument files produced by libreoffice are not compressible (not that much, anyway). They are already zip files. Their redundancies should have been removed by zipping.
Specifically, one expects that svg images are deflated into the libreoffice files, meaning that the resulting opendocument file are compact.

I'll mark this as enhancement request.
Should it be marked as NEW too?
Since this is very easy to verify, vector graphics is more and more widely used, and no-one wants files that take more space than needed on (paid) cloud storage, sd cards or usb-pen-disks, I'm changing unconfirmed -> new.
It's not 'enhancement,' one can reasonably expect compression in a ZIP file.
Actually bug 71622 is a dupe, but because the commit that fixed the issue I'll mark this one as duplicate of it. Otherwise it'll be difficult to link and track changes etc.
Good news is that it is fixed ;-).
