macos titlebar color

[rupisaini123]

In Tauri 2, the title bar on mac have solid color initially, but when scrolling it turns transparent and you can see content scrolling under it.
Hopefully this video would make more sense!

I would like to make sure that the title bar keep the solid color for the bar, like whatever it was on without any scroll.

tried using "titleBarStyle": "Overlay" in tauri.conf.json, but using it remove the whole bar.

Really appreciate all help in advance :)
