If virtualtext.vim is autoloaded first, it will link ALEVirtualTextWarning to ALEWarning. But ALEWarning is not initialized yet, so it will create ALEWarning, but with no color definition set. Shortly after, highlight.vim is autoloaded, which would usually link ALEWarning to SpellCap, but only if ALEWarning is not already set. However since ALEWarning is already initialized due to the previous link, we skip this and never actually come around to properly initializing it. We fix this by initializing all highlight groups in highlight.vim, thus satisfying the dependency of ALEVirtualTextWarning being initialized after ALEWarning. Fixes #3585
