Auto imports doesn't work in script setup template

[beqacrc]

Note

// src/utils/lodash.ts
export const dummy = () => true;

export const _ = {
   dummy() {
     return true
   }
}

<script setup lang="ts">
console.log(dummy) // this works
</script>

<template>
{{ _.dummy }} this doesn't work
</template>

Describe the bug

When using unplugin-auto-import in a Vite project to automatically import dependencies, the _.isArray function from a file (src/utils/lodash.ts) is working correctly in the script context but fails in the template.

The issue manifests as follows:

In the script section (<script setup>), _.isArray is correctly imported and works as expected.
In the template section (), _.isArray results in unexpected behavior, where the condition does not behave as expected.

to

export const $_ = { ... }

and it worked.

but can't figure out why

Same issue

[minht11]

Experiencing this issue too.

[beqacrc]

I think _ is vue compiler's reserved variable or something like that

[minht11]

I have issue with m variable and mm, didn't try other. I would dare to assume that auto imports do not work in template at all.
