[Donion] [2.0.9] Switching items in Factoriopedia resumes music during pause

[gyorokpeter]

Reproduction:
- Make sure the music is playing
- Open Factoriopedia
- Pause the game (which makes the music stop)
- Switch to an entry that has a simulation (e.g. "Item on ground")

Actual behavior:
- The music restarts, until re-pausing or using the "Pause music" hotkey

Expected behavior:
- The music should not restart out of the blue.

Moving this to Minor Issues as the fix for this seemed too annoying when I looked at this the last time and it is indeed a minor issue.

After looking into this again I came up with a solution I am satisfied with. Fixed for 2.1. Thanks for the report(s).
