• Make sure this is a Vite issue and not a framework-specific issue. For example, if it's a Vue SFC related bug, it should likely be reported to https://github.com/vuejs/vue-next instead.

Describe the bug

If a plugin adds another plugin via the config() hook, then the "inner" one will be ignored. Only the outer plugin will be added. My goal is to create a wrapper plugin for Preact applications that automatically sets up the prefresh plugin, devtools bridge and some custom SSR stuff.
