[bug] `TauriEvent.DRAG_DROP` don't fire on Arch Linux with Wayland

Describe the bug

When dragging files to Tauri apps on Arch Linux, the Tauri app can fire DRAG_ENTER, DRAG_OVER and DRAG_LEAVE events, but not DRAG_DROP.

Reproduction

On Arch Linux, create a Tauri + Vue.js app with pnpm create tauri-app
Follow the instructions to install the dependencies

Replace the src/App.vue file with:

<script setup lang="ts">
import {
  listen,
  TauriEvent,
  type Event,
  type UnlistenFn,
} from "@tauri-apps/api/event";
import { onMounted, onUnmounted } from "vue";
let unlistenFns: UnlistenFn[] = [];

onMounted(async () => {
  const logEvent = (e: Event<unknown>) => {
    console.log(e.event, e.payload);
  };
  unlistenFns = await Promise.all([
    listen(TauriEvent.DRAG_ENTER, logEvent),
    // DRAG_OVER works but produces a lot of events, so we don't log them
    // listen(TauriEvent.DRAG_OVER, logEvent),
    listen(TauriEvent.DRAG_LEAVE, logEvent),
    listen(TauriEvent.DRAG_DROP, logEvent),
  ]);
});
onUnmounted(() => {
  for (const unlistenFn of unlistenFns) {
    unlistenFn();
  }
  // clear the array
  unlistenFns.length = 0;
});
</script>

<template>
  <h1>Drag some files here</h1>
</template>

Run the app with pnpm tauri dev.
Press Ctrl + Shift + I to open the DevTools window.
Drag files to the app window and drop them.

Expected behavior

The app should produce one tauri://drag-enter event and one tauri://drag-drop event for each file.

But no tauri://drag-drop event is fired on my side.

I have also checked with CrabNebula DevTools, only tauri://drag-enter, tauri://drag-over and tauri://drag-leave are filed.
