warning animated pdf

SUMMARY
Thanks for supporting animated Beamers in okular!

I have come to an unexpected situation, where this animated PDF plays well in Okular:
https://texample.net/media/tikz/examples/PDF/animated-definite-integral.pdf

which uses:
`\begin{animateinline}[loop, poster = first, controls, palindrome]{2}`

But this one does not:
https://tud.qucosa.de/api/qucosa%3A29620/attachment/ATT-1/ (page 6)

that uses:
`\begin{animateinline}[controls]{1}`

and gives the warning seen in the attachment.

Both of them play well in Adobe Reader.

Do you see a similar problem? I am using version 20.12.3
Are there plans to support this type of animations in the future? (As I can not edit that published PDF any more)

Backup info: https://community.kde.org/GSoC/2019/StatusReports/Jo%C3%A3oNetto

STEPS TO REPRODUCE
1. Open PDF from first link above. Plays well.
2. Open PDF from second link above (page 6). Does not play.

OBSERVED RESULT
Second PDF animation does not play.

EXPECTED RESULT
Both should work

SOFTWARE/OS VERSIONS
Ubuntu 19 (snap version of Okular)
