I'm using Spotify (18.104.22.168.gf6bc1b6b) for macOS Mojave (10.14.2 (18C54)). I noticed when listening to the Hot Country playlist that the video would scroll up out of the screen without scrolling the playlist content along with it. This only occured when my mouse hovered over the video. If I scrolled while hovering over the song list in the playlist, the whole page would scroll normally.
