Using the music block like this:

[[block]]
block = "music"
on_collapsed_click = "spotify"

After clicking on it to launch spotify and starting music playback,
going full-screen in i3 will cause it to pause music/freeze.

I reckon this is caused because spotify is lauched as a child process of i3status-rust, and going full-screen suspends both processes.

Launching spotify by other means, avoids this issue, but loses the convenience of the single interface for music control.

$ i3status-rs --version
i3status-rs 0.12.0
