rewind does not work with alternative REACT_APP_MEDIA_ROOT_URL

Presentation located on Object Storage

On Ubuntu 18.04 we compiled v.5.0.2 using nodejs 18, npm 9.9.2
git clone https://github.com/bigbluebutton/bbb-playback/tree/v5.0.2

we did following steps.

BBB_PLAYBACK_HOMEPAGE=playback/presentation/2.3
BBB_PLAYBACK=/var/bigbluebutton/$BBB_PLAYBACK_HOMEPAGE
export REACT_APP_BBB_PLAYBACK_BUILD=a8f5a72
npm install
REACT_APP_MEDIA_ROOT_URL="https://s3-endpoint.org/published/presentation" npm run-script build

After files copied to
/var/bigbluebutton/playback/presentation/2.3
try to play presentation.
Playback starts
pressing rewind button returns to 0 time point (Safari or Firefox, which works by small step), and progress bar rewind does not work at all.

I do not see any related errors in browser's developers console.

Any ideas? or may be I missed something?

seems it's happens only on some recordings.
how to check what's going wrong there?
