JS command() API is not display more than 2 lines of messages for WPF solution with CEFSharp V84

Question

enter image description here在此处输入图像描述


<!DOCTYPE html>
<html>
<body>

<h1>HTML DOM Events</h1>
<h2>The onclick Event</h2>


<button onclick="myFunction()">Confirm</button>


<script>
function myFunction() {
        var message = "You have selected:";
        message += "Stmt1 \r\n stmt2 \r\n stmt2";
        message += "\r\n";
        message += "stmt2stmt2stmt2stmt2stmt2stmt2stmt2stmt2stmt2stmt2stmt2\n";
        message += "stmt2stmt2stmt2stmt2stmt2stmt2stmt2stmt2stmt2stmt2stmt2stmt2";
        status = confirm(message);
}

</script>

</body>
</html>

Here after 3rd line of the message, it is hidden.Also window size is not increasing to contain full text.在消息的第 3 行之后，它是隐藏的。另外 window 大小没有增加以包含全文。 Same is working fine with IE.同样适用于 IE。

using System.Windows;

namespace CefSharp.Wpf.Example.Handlers
{
    public class JsDialogHandler : CefSharp.Handler.JsDialogHandler
    {
        protected override bool OnJSDialog(IWebBrowser chromiumWebBrowser, IBrowser browser, string originUrl, CefJsDialogType dialogType, string messageText, string defaultPromptText, IJsDialogCallback callback, ref bool suppressMessage)
        {
            var b = (ChromiumWebBrowser)chromiumWebBrowser;

            b.Dispatcher.InvokeAsync(() =>
            {
                if (dialogType == CefJsDialogType.Confirm)
                {
                    var messageBoxResult = MessageBox.Show(messageText, $"A page at {originUrl} says:", MessageBoxButton.YesNo);

                    callback.Continue(messageBoxResult == MessageBoxResult.Yes);
                }
                else if(dialogType == CefJsDialogType.Alert)
                {
                    var messageBoxResult = MessageBox.Show(messageText, $"A page at {originUrl} says:", MessageBoxButton.OK);

                    callback.Continue(messageBoxResult == MessageBoxResult.OK);
                }
                else if (dialogType == CefJsDialogType.Prompt)
                {
                    var messageBoxResult = PromptDialog.Prompt(messageText, $"A page at {originUrl} says:", defaultPromptText);

                    callback.Continue(messageBoxResult.Item1, userInput: messageBoxResult.Item2);
                }
            });

            return true;
        }
    }
}

//Assign your handler to the ChromiumWebBrowser instance
browser.JsDialogHandler = new CefSharp.Wpf.Example.Handlers.JsDialogHandler();
