Generic type definition of null | undefined gets removed during Vite build

[jousi592]

I cant figure out, why when I run vite build, does my generic component <script setup lang="ts" generic="V extends string | number | null | undefined"> loose its null | undefined types and gets transformed after build to declare const _default: <V extends string | number>.

I need the null and undefined types to persist, but cant figure out how to achieve this, any ideas? 🙏
