[bug] webview.delete_cookie not working

[AlloryDante]

Describe the bug

I tried to clear previous session of a remote website (roblox.com) using a command:

#[tauri::command]
async fn delete_session(window: tauri::WebviewWindow) {
  
    let cookies = window.cookies().unwrap();
    for cookie in cookies {
            println!("{:?}", cookie);
            let webview = window.get_webview_window("main").unwrap();
            webview.delete_cookie(cookie).unwrap(); 
            println!("Deleted cookie");
       
    }


    window.eval("window.location.replace('https://www.roblox.com/')").unwrap();
}

I used the window.TAURI.core.invoke("delete_session") to execute the command.

In the tauri console I can see bunch of cookies getiing deleted but they are still present when the the page navigates to the website.

In case there is needed here is my main script:

fn main() {
    tauri::Builder::default()
        .plugin(tauri_plugin_store::Builder::new().build())
        .plugin(tauri_plugin_http::init())
        .invoke_handler(tauri::generate_handler![
            add_roblox_account, 
            notify_login_success,
            handle_roblox_account,
            delete_session
        ])
        .setup(|app| {
            let window = app.get_webview_window("main").unwrap();
            let webviews = app.webview_windows();
            Ok(())
        })
        .run(tauri::generate_context!())
        .expect("error running tauri app");
}

Stack trace

Additional context

I want to be able to delete the previous session from a remote website (delete the cookies).

[Legend-Master]

Seems like the cause is that the cookie crate removed the leading . in the domain name which webview2 APIs expect

And there's currently no way for us to check it, see rwf2/cookie-rs#240
