WKWebView如何在显示键盘时禁用adjustedContentInset？

import UIKit
import WebKit

class ViewController: UIViewController {
    var webView: WKWebView!

    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 初始化WKWebView
        webView = WKWebView(frame: self.view.frame)
        self.view.addSubview(webView)
        
        // 加载网页
        let url = URL(string: "https://example.com")!
        let request = URLRequest(url: url)
        webView.load(request)
        
        // 注册键盘事件监听
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIResponder.keyboardWillShowNotification, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(_:)), name: UIResponder.keyboardWillHideNotification, object: nil)
    }

    @objc func keyboardWillShow(_ notification: Notification) {
        // 获取键盘高度
        if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
            // 设置WKWebView的contentInset和scrollIndicatorInsets，忽略键盘高度
            webView.scrollView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
            webView.scrollView.scrollIndicatorInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
        }
    }

    @objc func keyboardWillHide(_ notification: Notification) {
        // 恢复默认的contentInset和scrollIndicatorInsets
        webView.scrollView.contentInset = UIEdgeInsets.zero
        webView.scrollView.scrollIndicatorInsets = UIEdgeInsets.zero
    }

    deinit {
        // 移除监听器
        NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillShowNotification, object: nil)
        NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillHideNotification, object: nil)
    }
}
