v0.40.0 template type problems

Hi,

Since upgrading to v0.40.0 some of my Vue component templates stopped detecting types, e.g. on hover where I see a type in v0.39.5 I don’t see it anymore in v0.40.0.

I also see some of variables, for example computed property defined in script setup marked as not used, even though I’m using them in the template.

Sorry for being sparse with the details, I just am not sure what else than version number and behavior I could provide 😊

[edit] I also found out that when I run Volar: Verify All Scripts in v0.40.0 I got about 5 errors, but I get none in v0.39.5 and I’m almost certain that errors are false positives.

I have the same issue, and every time the variable/function is used in a v-else block.

<script setup lang="ts">
  const thing = 42; // 'thing' is declared but its value is never read. ts(6133)
</script>

<template>
  <div v-if="true"></div>
  <div v-else>{{ thing }}</div>
</template>

The target in my tsconfig is indeed set to 2.7 already, but that is a really good thought!

I also just tested out enabling the experimentalImplicitWrapComponentOptionsWithVue2Extend option and unfortunately it still does not fix template type checking in components not using <script setup>.

Really appreciate the additional information on a version locking feature too, it’s true that Microsoft supporting extension version locking in their workspace recommendations would also be an excellent solution. Understandable with the speed of iteration that now maybe wouldn’t be the best time for that feature. Still hoping for it one day!
