How to remove this selection blue when generating the PDF?

Question

I have a system that marks the text, creating a span with the notes, I’m using a lib to export PDF, but when it loads the DOM to export to PDF, it’s keeping this blue check mark, very strange. Have some way to lock that "Selection" event in the text while having the pdf exported?

Here the HTML that is sent to generate the PDF.

This is the Lib.

This is the code that takes this HTML:

var content = "aqui entra como string o conteúdo do link acima";

var worker =  html2pdf();

                        worker.set(opt)
                        .from(content)
                        .toPdf()
                        .get('pdf')
                        // 
                        .then(function (doc) {

                          var totalPages = doc.internal.getNumberOfPages();
                          for (var i=1; i<=totalPages; i++) {

                           if (i == 1) {
                             doc.setPage(1);
                             //cria a legenda
                              doc.setFontType("bold");
                              doc.text(330, 40, 'Matéria: ');
                              doc.setFontType("normal");
                              doc.text(380, 40,  'No onno nono nononono');

                              doc.setFontType("bold");
                              doc.text(330, 60, 'Atividade: ');
                              doc.setFontType("normal");
                              doc.text(390, 60, 'Nonnono onno nonono');
                              doc.setFontSize(12);
                              doc.setFontType("normal");
                              doc.setPage(i);
                           } else {
                               doc.setPage(i);

                           }

                          }


                        })

                        .save();
