[bug] Titlebar shows when it should not

[Waradu]

Describe the bug

tauri v2 with Nuxt v3

so I want to create full monitor confetti:

somewhere in the code:

const webview = new WebviewWindow('confetti', {
  url: '/confetti',
  transparent: true,
  decorations: false,
  alwaysOnTop: true,
  focus: false,
  fullscreen: true,
  shadow: false,
  skipTaskbar: true,
})

confetti.vue:

<template>
</template>

<script lang="ts" setup>
import { getCurrentWindow } from "@tauri-apps/api/window";

definePageMeta({
  layout: false,
});

const { proxy } = useScriptNpm({
  packageName: 'js-confetti',
  file: 'dist/js-confetti.browser.js',
  version: '0.12.0',
  scriptOptions: {
    //@ts-ignore
    use: () => typeof window.JSConfetti !== 'undefined' && new window.JSConfetti()
  },
})

getCurrentWindow().setIgnoreCursorEvents(true)

onMounted(async () => {
  proxy.addConfetti({
    confettiRadius: 6,
    confettiNumber: 500,
  })

  setTimeout(() => {
    getCurrentWindow().close()
  }, 3000);
})
</script>

but as soon as I "interact" with the window (obviously I click through (tested this) and even if something on another monitor is interacted with) this happens:

2024-09-18.15-48-07.online-video-cutter.com.mp4

the "titlebar" appeared as soon as I clicked (titlebar is not interactable)

Reproduction

Create a tauri app with nuxt and paste in the code from above (@nuxt/scripts package is required)

Expected behavior

No titlebar it should just stay invisible
