When testing #13142, I realized that timer for time spent on a twitch video is not resumed when you click PLAY after pausing a video

1. Watch a twitch video; confirm time spent is showing in ledger
2. Click pause; confirm time spent was updated
3. Click play again; wait for a minute
4. Notice time does not increment

Seeing a different behaviour on Windows.
Visited this link and started playing video https://www.twitch.tv/videos/230977648
Played the video for 3min20sec and paused, ledger showed 3min52secs as time spent
Paused the video for 2 mins and then resumed to play
Played the video for 4min53sec and paused, ledger showed 6min39secs

Even seeking video to a different position the time spent is recorded

Tried your scenario, this is what happened for me:

Played the video for 3min20sec and paused, ledger showed 3min21secs as time spent
Paused the video for 2 mins and then resumed to play
Played the video for 4min53sec (which is total of 8m13s) and paused, ledger showed 8min15secs

That 2s more is expected and happens because of the nature that we are logging twitch time
