[v2] context menu disappears on button release

[rtbo]

Describe the bug

When I popup a context menu using JS API @tauri-apps/api/menu, the menu shows normally, but is closed as soon as the right mouse button is released. This makes it quite unusable.

Reproduction

Svelte minimal example:

<script lang="ts">
  import { Menu, MenuItem } from '@tauri-apps/api/menu';

  async function contextMenu() {
    const menu = await Menu.new();

    menu.append(
      await MenuItem.new({
        text: 'Open',
        action: async () => {}
      })
    );

    await menu.popup();
  }
</script>

<div>
  <p on:contextmenu|preventDefault={contextMenu}>test</p>
</div>

Expected behavior

The context menu should behave just like with any other toolkit.
