My Question or Issue
After hiding / minimizing Spotify using Command+W (on macOS), play/pause functionality with the space bar does not work until clicking on the Spotify UI to fully focus the application. Other Spotify hotkeys such as Command+Left Arrow and Command+Right Arrow still function in this state, but not the space bar for play/pause. A demonstration of the issue can be found below.
