I love the background audio idea for sidecar blocks. It's a useful feature for adding ambient sounds of places (and many other things too, I'm sure). However, when you scroll past a block the sound abruptly cuts off and doesn't match the smooth transition on the visual side.
Could background audio fade in/out as you scroll through the page? And/or crossfade with audio in the next or previous sidecar block?
Thank you for considering this.
