The base64-encoded payload apparently is a PNG image. And from what
little I know about PNG, it looks plausible to me that there can be
different (compressed) PNG content that decompress to identical raw
data, and that the LibreOffice code would be allowed to generate
differing (compressed) PNG content for the above data:image/png URL payload.
If that assumption is right, the above assertXPath check would be bogus.
Can somebody clarify, and clarify what the test should actually verify?
