hdr.insertOoxml 第一次不行

Question

当我将此加载项部署到 MS Word 应用程序时，我必须多次单击该按钮才能最终成功地从 hdr.insertOoxml() 到运行。有时不得不点击这个功能超过 4 次（见下面的代码）。虽然，这似乎在 Word 365 的网络版本中工作得更好（尽管仍然不完美）。请指教，谢谢！

function applyletterhead() {
    Word.run(function (context) {


        var departmentLH = document.getElementById("lh-department").options[document.getElementById("lh-department").selectedIndex].value;


        var sameLHCB = document.getElementById("sameLH");
        var secondHT = document.getElementById("secondH").value;

        if (sameLHCB.checked === true) {
            toDataURL(departmentLH + '_First.png', function (dataUrl) {
                var myOOXMLRequest = new XMLHttpRequest();
                var myXML;
                myOOXMLRequest.open('GET', '_SP_letterhead_First.xml', false);
                myOOXMLRequest.send();
                if (myOOXMLRequest.status === 200) {
                    myXML = myOOXMLRequest.responseText;
                    myXML = myXML.replace('#####secondH#####', secondHT);
                    myXML = myXML.replace('#####imagepath#####', dataUrl.replace('data:image/png;base64,', ''));
                }
                let hdr = context.document.sections.getFirst().getHeader("Primary"); //returns Word.Body type
                hdr.clear();
                hdr.insertOoxml(myXML, 'Replace');
            });
        }
        else {
            toDataURL(departmentLH + '_First.png', function (dataUrl) {
                var myOOXMLRequest = new XMLHttpRequest();
                var myXML;
                myOOXMLRequest.open('GET', '_SP_letterhead_First.xml', false);
                myOOXMLRequest.send();
                if (myOOXMLRequest.status === 200) {
                    myXML = myOOXMLRequest.responseText;
                    myXML = myXML.replace('#####secondH#####', secondHT);
                    myXML = myXML.replace('#####imagepath#####', dataUrl.replace('data:image/png;base64,', ''));
                }
                let hdr = context.document.sections.getFirst().getHeader("FirstPage"); //returns Word.Body type
                hdr.clear();
                hdr.insertOoxml(myXML, 'Replace');
                console.log("First: ", myXML);
            });

            toDataURL(departmentLH + '_Primary.png', function (dataUrl) {
                var myOOXMLRequest = new XMLHttpRequest();
                var myXML;
                myOOXMLRequest.open('GET', '_SP_letterhead_Primary.xml', false);
                myOOXMLRequest.send();
                if (myOOXMLRequest.status === 200) {
                    myXML = myOOXMLRequest.responseText;
                    myXML = myXML.replace('#####secondH#####', secondHT);
                    myXML = myXML.replace('#####imagepath#####', dataUrl.replace('data:image/png;base64,', ''));
                }
                let hdr = context.document.sections.getFirst().getHeader("Primary"); //returns Word.Body type
                hdr.clear();
                hdr.insertOoxml(myXML, 'Replace');
                console.log("Primary: ", myXML);
            });
        }

在 hdr.insertOOXML 的第一个和最后一个调用下方添加对 return context.sync() 的调用。
