Audio: Removing upcoming anime resumes music playback

[AnnsAnns]

Steps to reproduce:

• Start some music, in this case I shortly listened to: https://notify.moe/soundtrack/LdHQC-fzg
• Pause the music
• Go into your upcoming anime
• Remove some anime from your collection
• The music starts playing again, without any visual changes to the music player. [Still shows the track as paused]

Expected behavior:

• Removing anime shouldn't affect the music playback.

Version:

• Firefox 77.0.1, 64Bit
