Pinpointing if this is a bug, and if so where...

[dsl101]

I'm not entirely confident of the architecture of my setup, but I have SublimeText 4, with LSP-vue (3.5.0), LSP-eslint (2.1.0), and LSP-typescript (2.13.2). For the most part, everything is working nicely. And then I noticed an issue in a legacy project, and spent a good deal of time trying to work out what broke. Then I checked it out in our most recent project, which is running the latest version of all the frameworks, libraries, etc and see the same thing. And full disclosure, it was Claude that eventually suggested that, given where I got to, this was a bug with the language server. It may not be—hence asking for more help here.

The issue is visible in this simple sfc:

<template>
  <button @click="handleClick" />
</template>

<script setup>
  const props = defineProps({
    meaning: {
      type: Number,
      default: 42,
    },
  })
</script>

If I go to the script block and type function h, I get the completion handleClick show up immediately, and all is well. However, if I change the props definition to a bare call:

<template>
  <button @click="handleClick" />
</template>

<script setup>
  defineProps({
    meaning: {
      type: Number,
      default: 42,
    },
  })
</script>

The completion no longer shows up at all. In both cases, I see warnings in the template section that handleClick is undefined, so the server is clearly picking that up, but it doesn't offer it as a completion in the second case.

Is this a misconfiguration on my part? Or is it actually something not working as it should?
