Description :octocat:
我想在spacemacs-purpose layer中只使用popwin，其他的packages有window-purpose，ivy-purpose的我不需要。然后在dotspacemacs-configuration-layers
(spacemacs-purpose :packages popwin)
Observed behaviour: 
但是实际情况是其他的packages也安装了，不清楚是不是因为是核心包的问题。chinese layer中使用packages keyword是生效的。
Expected behaviour: 
️ 
It should be just popwin installed…
