Error when using with unplugin-vue-components and SSR

[AaronBeaudoin]

Describe the bug

Minimal reproduction here (with steps in README):
https://github.com/AaronBeaudoin/vite-plugin-md-issue-weakmap-key

Description

I have a minimal Markdown.md file:

<Example/>

Where <Example/> is being auto-imported by unplugin-vue-components from ./components/Example.vue:

<template>
  Example
</template>

During development, going to the page shows the text "Example" as expected.

However, after building for SSR, going to the page results in the following error:

[Vue warn]: Failed to resolve component: example
If this is a native custom element, make sure to exclude it from component resolution via compilerOptions.isCustomElement.

The reproduction Aaron provided uses Vite's SSR API.

This means that this bug affects all Vite frameworks (vite-plugin-ssr - #422, Nuxt, ...).

Just bringing attention back to this issue at the 3 week mark.

@AaronBeaudoin please try Release v0.22.0 and see if it fixes your error? If not then do note @brillout comment that there error is directly related to a different repo. Reopen if it is still an issue ok?

[brillout]

The latest tag still points to the 0.21.x release branch. So I guess the 0.22.x branch is beta? (I couldn't find any mention of 0.22.x in the readme.)

@brillout i've been trying to clear out some dependencies so I can do another release on this ... I had thought I'd released v22 though but I'll check in the next day or too. Sorry for the delays.
