Someone else reported the same issue in our Discord server, apparently, it's just how the 'auto-pause' feature works. It pauses whatever's playing on the Player whenever it detects another media playing with sound. So, when that media goes silent for a moment, the Player resumes playing.
You can try picking the setting shown in the attached image to at least make it happen less.
This will make it so that the Player will resume playing after 5 seconds of silence.
