The problematic PDF

SUMMARY

When opening the attached PDF, which was exported from LibreOffice Writer 6.7.0.3, the embedded video is has the wrong size and position (see attached screenshot).

I am also attaching the ODT from which it was exported.

STEPS TO REPRODUCE

1. Open the attached PDF (video.pdf)

OBSERVED RESULT

Embedded video is shown at the wrong size and position. It is too small, and too much to the left. 

EXPECTED RESULT

The video should be shown positioned and sized as shown in the attached screenshot from LibreOffice Writer. In Okular, one can also see a preview still image: That is the position/size which should be used for the video itself as well.

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: Kubuntu 18.04
KDE Plasma Version: 5.12.9
KDE Frameworks Version: 5.44
Qt Version: 5.9.5

ADDITIONAL INFORMATION

tosky on #okular @ freenode also helped test on Okular 1.9.3, and presumably with much newer Plasma/KF5 than me, and saw the same problem:
 
    22:01 < tosky> estan: I see the same issue with the last current stable (1.9.3 release one month ago; a new one will be released in less than one month)

So I'm setting Version of this bug to 1.9.3.
