Cannot drag tauri app window on MacOS when titleBarStyle is set to Overlay

[cgaege]

Describe the bug

On MacOS Sonoma, I cannot move the application window of my tauri app when titleBarStyle is set to Overlay:

tauri.conf.json

 "windows": [
      {
        "title": "tauri-app",
        "width": 800,
        "height": 600,
        "titleBarStyle": "Overlay"
      }
    ]

Reproduction

1. Generate a minimal tauri app (accept all default values) npm create tauri-app@latest

2. Run npm install in tauri-app cd tauri-app npm install

3. Edit src-tauri/tauri.conf.json and add titleBarStyle: Overlay to the windows property section:

"windows": [
      {
        "title": "tauri-app",
        "width": 800,
        "height": 600,
        "titleBarStyle": "Overlay"
      }
    ],

4. Run tauri app npm run tauri dev

Faulty behaviour: The application window cannot be moved.

Maybe, did you add the data-tauri-drag-region attribute the issue was talking about to your titlebar-ish element? Just making sure cause you didn't mention it, but it is required to be able to move your app.
