[desktop_webview_window] Can't open URL about:srcdoc on macOS

[duarte-costa]

Can't open URL about:srcdoc on macOS... Is there any reason why the URL "about" is not on the scheme guard block? Thank you.

On WebViewLayoutController.swift:

extension WebViewLayoutController: WKNavigationDelegate {
  func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
    guard let url = navigationAction.request.url else {
      decisionHandler(.cancel)
      return
    }

    guard ["http", "https", "file"].contains(url.scheme?.lowercased() ?? "") else {
      decisionHandler(.cancel)
      return
    }

    methodChannel.invokeMethod("onUrlRequested", arguments: [
      "id": viewId,
      "url": url.absoluteString,
    ] as [String: Any])

    decisionHandler(.allow)
  }
