How can stop event propagation in Vue 3 to the root component

I’ve created several components that communicate with each other using custom events.

The issue is that I’m having difficulties with event propagation. I have an App.vue component that instantiates a GeneriqueButton component, which in turn instantiates a BaseButton component. I’ve added an event listener on GeneriqueButton with the .stop modifier to prevent event propagation to App.vue, but the event still bubbles up to App.vue, I’ve message in my console.

I don’t understand why the event continues to propagate despite the use of the .stop modifier. I’ve verified that the event is emitted from BaseButton, but it’s still captured by App.vue.

Here’s the code for the three components:

App.vue :

<template>
  <GeneriqueButton @base-button="printConsole"/>
</template>

<script setup>
import GeneriqueButton from './GeneriqueButton.vue'
function printConsole(event) {
  console.log('App.vue : BaseButton clicked !', event)
}
</script>

GeneriqueButton.vue

<template>
  <BaseButton @base-button.stop="printConsole" />
</template>

<script setup>
import BaseButton from './BaseButton.vue'
function printConsole(event) {
  console.log('GeneriqueButton.vue : BaseButton clicked !', event)
}
</script>

BaseButton.vue

<template>
  <button type="button" @click="$emit('base-button', $event)">
    Click me
  </button>
</template>

I use console.log in App.vue and GeneriqueButton.vue, each click on button I have 2 logs in my console.

Do you have any idea what might be causing this event propagation issue? Do you have any suggestions on how to fix it?

Thank you in advance for your help.
