I noticed an unexpected audio behavior while I was working on my project. This is not critical, so please check when you have time.
1. Open https://playcanvas.com/project/367166/overview/mmd-on-html5 with Chrome
2. Play all scene until the music ends and the characters become still after they bow.
3. Switch to another Chrome tab. Then switch back to the PlayCanvas tab.
4. Notice the music starts to play again from the beginning even the "this.entity.audiosource.play("music.ogg");" (audio.js line 10 which starts the musin in the program) is not called.
