SUMMARY:
--------

Okular is unable to render AVIF images directly from within a ZIP container,
but it can render them correctly when the images are extracted. This suggests a
potential issue with Okular's handling of ZIP containers with AVIF images
within them.

STEPS TO REPRODUCE
1. `avifenc Test_Material.jpg Test_Material.avif`
2. zip it through cmdline or from middle click window `Compress > Compress to
"Test_Material.zip"`
3. open the zip file with okular and see that the image is being extremely
enlarged (vertically)
4. open context window with middle click and "Extract here" then open the
folder with okular and it will render the avif image properly.
5. try opening the `Test_Material.zip` that has the avif image in it with MPV
and MPV wont have any issues with it.

OBSERVED RESULT

Okular renders an extremely enlarged (vertically) image

EXPECTED RESULT

Okular should render AVIF files without any issues.
