Types problem when using `<script setup>` alongside normal `<script>` since `v1.8.14`

[Yizack]

Hello, I have a types problem in vue projects where <script setup> is being used alongside the normal <script>. Since v1.8.14 and v1.8.15, property types inside the normal <script> aren't being recognized. Before v1.8.14 using both at the same time used to work without any problem and properties were all recognized, I don't know if the changes in recent versions broke something or if this is intended to encourage not using both definitions. I'll be looking forward to your response thanks <3

And when removing <script setup> the problem disappears

Example code:

<script setup lang="ts">
// some code
</script>

<template>
  {{ hello_world }}
</template>

<script lang="ts">
export default {
  data () {
    return {
      hello_world: "Hello World!"
    };
  }
};
</script>
