Ckeditor从剪贴板拖放图像上传和粘贴图像在WebView JavaFX内部不起作用

如何解决Ckeditor从剪贴板拖放图像上传和粘贴图像在WebView JavaFX内部不起作用

我在应用程序中使用了ckeditor4。从剪贴板粘贴图像，然后使用ckeditor中的“ uploadimage”插件拖放。在浏览器中工作正常。如果我尝试从javafx webview访问同一页面。它不起作用。它甚至不会触发“ fileUploadRequest”方法。

function activateCkeditor(){
    //Intializing ckeditor 
    CKEDITOR.disableAutoInline = true;
        var defToolbar = [{ name: 'basicstyles',groups: [ 'basicstyles' ],items: [ 'Bold','Italic','Underline','Strike','Subscript','Superscript'] },{ name: 'paragraph',groups: [ 'list'],items: [ 'NumberedList','BulletedList' ] },{ name: 'insert',items: [ 'Image']}];
        var inlineEditor = CKEDITOR.inline(id,{
            extraPlugins : 'sharedspace,uploadimage,uploadwidget',removePlugins: 'floatingspace,elementspath,magicline,wsc,scayt,liststyle,tableselection,tabletools,tableresize,contextmenu',sharedspaces: {
                       top: 'ckEditBar'
                     },toolbar: defToolbar,enterMode : CKEDITOR.ENTER_BR,shiftEnterMode : CKEDITOR.ENTER_BR,disallowedContent : 'div',imageUploadUrl : 'uploadImageAsNote.action',uploadUrl : 'uploadImageAsNote.action',startupFocus: false,readOnly : false,title : false,allowedContent: false,pasteFromWordPromptCleanup : false,pasteFromWordRemoveFontStyles : true,forcePasteAsPlainText : true,ignoreEmptyParagraph : true,});
        
        
    fnImageUpload(obj,inlineEditor);//binding event
}
    

function fnImageUpload(obj,editor){
    editor.on("contentDom",function() {
        editor.document.on("DOMNodeRemoved",function(e) {
            if($(e.target).hasClass("minImageTag")){
                $(".uploadImgIcon"+$(e.target).attr("imageid")).remove();
            }
        }); 
    });
    editor.on( 'fileUploadRequest',function( evt ) {
        console.log("inside fileuploadRequest");    
        var fileLoader = evt.data.fileLoader,formData = new FormData(),xhr = fileLoader.xhr;

         // if (Math.round(parseInt(fileLoader.file.size) / (1024 * 1024)) > 2) { // make it in MB so divide by 1024*1024
         if (fileSize>=2048) { // make it in MB so divide by 1024*1024
              alert($("#imageUploadLimitAlert").text());
              evt.cancel();
