Score is lost if Moodle session is disconnected in the background

[Urpokarhu1]

Hello,

If you f.ex. use Moodle default sessiontimeout 2 hours -> open h5p for 3 hours -> complete it and get your grade -> change page -> Moodle will ask you to login again -> nothing is saved and H5P doesn't warn that session have been disconnected in the background.

H5P should check periodically if the Moodle session is alive and warn user if it has been disconnected.
