Resuming media plays from incorrect time

[ChocOranger]

Describe the bug
When resuming a movie the time displayed in Kodi's context popup for resume is correct (eg Resume from 00:13:45) will actually resume from around a minute or so before that time (eg 00:12:45). Actual time appears to vary depending on how far played (eg 1:08:31 resumes @ 1:07:07)
The jumpback on resume time is the default of 10 seconds.
I originally posted on the Jellyfin forum https://forum.jellyfin.org/t-jellyfin-kodi-addon-resuming-media-jumps-back-about-a-minute with one other person replying they had the same issue. Nobody replied it was working correctly for them.

To Reproduce

1. Play a movie
2. Stop the movie part way through noting the time played
3. Restart the movie and the resume from should be the time played in step 2 minus jumpback time.
4. Actual restart position is around a minute earlier than displayed in the Kodi context menu.

Expected behavior
Movie restarts from the stopped time minus the jumpback on resume time.

Logs
Couldn't see any relevant log errors

I can confirm this problem.
It occurs to me since I switched from "native paths" to "AddOn mode" due to this discussion:
jellyfin/jellyfin#11654

I never switched back to "native paths" because I want to test "AddOn mode" more, if I can find anymore issues.
And I think, that this IS an issue with AddOn mode - I never experienced this behavious with native paths.

More Info: I'm pretty sure, that the resuming time is always exactly one minute before the actual stopping time.
So the configured time isn't used, it's always 60 seconds instead.
