字体大小不适用于tinymce

Question

我刚刚在tinymce中添加了字体大小选项。在html编辑器中，它显示正确更改的字体大小，但它不保存更改的内容。我不认为xss过滤是问题，因为其他格式化工作（粗体，斜体，......）。

我像这样初始化tinymce

<script type="text/javascript">
            tinymce.init({
                selector: "textarea", theme: "modern", width: 930, height: 300,                
                plugins: [                    
                    "advlist autolink link image lists charmap print preview hr anchor pagebreak",
                    "searchreplace wordcount visualblocks visualchars insertdatetime media nonbreaking",
                    "table contextmenu directionality emoticons paste textcolor responsivefilemanager"
                ],
                toolbar1: "undo redo | bold italic underline | sizeselect | fontsizeselect | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | styleselect",
                toolbar2: "| responsivefilemanager | link unlink anchor | image media | forecolor backcolor  | print preview code ",
                image_advtab: true,
                external_filemanager_path: "/Scripts/filemanager/",
                filemanager_title: "Responsive Filemanager",
                external_plugins: {"filemanager": "/Scripts/filemanager/plugin.min.js"}
            });
        </script>
