How to catch IPX errors and show fallback with `NuxtImg` or `NuxtPicture`?

I tried to use @error on NuxtImg and <NuxtErrorBoundary> component, but nothing works:

<template>
 <nuxt-error-boundary @error="handleError">
  <nuxt-img
    @error="handleError"
    @load="handleLoad"
    :src="url"
  />
  <template #error="{ error }">
    <p>This is never displayed: {{ error }}</p>
  </template>
</nuxt-error-boundary>
</template>

<script lang="ts" setup>
  const handleError = (e) => {
    // never gets printed, even if no image is displayed and ipx had an error
    console.log("error", e)
  }
  
  const handleLoad = (e) => {
    // gets printed when image is loaded successfully
    console.log("load", e)
  }
</script>

Here is the full IPX error (also see screenshot):

{
  "error": {
    "message": "[400] [IPX_INVALID_IMAGE] Cannot parse image metadata: http://localhost:4566/<image-url>"
  }
}

The issue names NuxtImg, NuxtPicture, NuxtErrorBoundary, and IPX but no repository files or tests. Reproduce the failed image case with the provided snippet, then trace how image errors propagate through these components. Done means establishing and documenting or correcting a reliable fallback and error-handling path for the reported IPX response.
