doesn't create filled TOC in downloaded docx

[lacera]

Hi! Help, please. This simple example (copied from codepen.io HTML block) doesn't create filled TOC in downloaded docx and i have no ideas, why :(
`

<script src="https://unpkg.com/docx@5.0.0-rc5/build/index.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/FileSaver.js/1.3.8/FileSaver.js"></script> Click to generate document

<script>
    function generate() {
        const doc = new Document();
      
        doc.addSection({
            children: [
                  new TableOfContents("Summary", {
                       hyperlink: true,
                       headingStyleRange: "1-5",
                 }),
                 new Paragraph({
                      text: "Header #1",
                      heading: HeadingLevel.HEADING_1,
                      pageBreakBefore: true,
                 }),
            ]
        });
        Packer.toBlob(doc).then(blob => {
            console.log(blob);
            saveAs(blob, "example.docx");
            console.log("Document created successfully");
        });
    }
</script>

Ah it does work for me, but you need to press that button:

This is a known issue, but I'm not sure how to fix it.

Then it displays like normal:

Check out demo 28: https://github.com/dolanmiu/docx/blob/master/demo/28-table-of-contents.ts

heh, i have two ways: open it in *nix LibreOffice (no result with broken TOC but other docx with filled TOC open with filled TOC) and open it in docs.google.com (no result too... but there i may update TOC and see it but this it dances with tambourine :) )

If you can find a way to fix it, please make a PR!

I would love to have this fixed also, but I suspect it is very hard.

I do not think it is possible actually, and thats by design. OOXML does not know about the concept of pages.
I have wrote an explanation on the related issue.
