Okular Epub Regression Screenshot

SUMMARY
I report this as major. Okular should be document viewer, but EPub missin all photos in epub document is a major issue. One cannot read computer articles that have screenshot and wikis in them. Document becomes useless without them.
There's absolutely no problem using mupdf and mupdf-gl. All photos are there.

STEPS TO REPRODUCE
1. Download PCLinux Magazine ePub (vol. 174, July 20021)
2. Scroll through the whole document using Okular

OBSERVED RESULT
No photos in ePub documents.

EXPECTED RESULT
Reintroducing Okular to display photos in ePub

SOFTWARE/OS VERSIONS

Linux/KDE Plasma:  Arch (not Manjaro)
KDE Plasma Version: 5.26.4
KDE Frameworks Version: 5.100.0
Qt Version: 5.15.7

ADDITIONAL INFORMATION
"Enable text Antialias"
"Enable graphics antialias"
"Enable tex hinting"
Should be turne on by default, so Okular displays readable documents, out of the box (its not 1995).

Since you don't know how to download publicly available magazine from PCLinuxOS (see original post) here I am going to teach you how to do it:

wget -c --prefer-family=IPv4 --no-use-server-timestamps --no-dns-cache --no-cache --no-cookies --secure-protocol=PFS 'https://www.pclosmag.com/download-epub.php?f=202107epub.epub' -O 'PCLinusOS Magazine that Okular Cannot Display-Missing Photos.epub'

> its not 1995

LOL, i was going to look at this issue, but I'm thinking I prefer to spend my spare time fixing some other bug where the reporter wasn't trying to be "funny"
