Content Control insertOoxml may not preserve numbering style in Office Online

[whekin]

Provide required information needed to triage your issue

Your Environment

• Platform [PC desktop, Mac, iOS, Office on the web]: Office on the web
• Host [Excel, Word, PowerPoint, etc.]: Word
• Office version number: current
• Operating System: Mac OS Sonoma
• Browser (if using Office on the web): Chrome

Expected behavior

Same as in the desktop version of Word. Also, same as if working with documents with simpler numbering style.

Current behavior

When working with the example document I get the following behavior in Word Online. Before inserting ooxml:

After inserting ooxml:

Link to the document (onedrive)

When using simpler numbering styles ooxml inserts as expected.

Steps to reproduce

Code to insert ooxml:

await Word.run(async (context) => {
    const selection = context.document.getSelection();
    const cc = selection.parentContentControl.load();
    cc.cannotDelete = false;

    await context.sync();

    const ooxml = cc.getOoxml();

    await context.sync();

    cc.getRange().insertOoxml(ooxml.value, "Replace");

    await context.sync();
});

Provide additional details

1. The example document already has a content control over 1.1 section
2. Selecting it and executing the code results in the issue in Word Online

Additionally, there inconsistent behavior of getOoxml in Word Online and Word for Mac. On Mac, the document body I get the w:sdt itself, while in Word Online I get the contents of w:sdtContent. The the images below I executed this code:

 await Word.run(async (context) => {
    const selection = context.document.getSelection();

    const cc = selection.parentContentControl.load();

    await context.sync();

    const ooxml = cc.getOoxml();

    await context.sync();

    const ccDocument = new DOMParser().parseFromString(ooxml.value, "text/xml");

    const document = ccDocument.getElementsByTagName("w:document")[0];

    const body = document.children[0];

    console.log(body);
});

Context

I'm developing an add-in for document automation. I want to toggle (hide/unhide) sections in a big list though the add-in. I've come up with a solution using content controls over each section, and then inserting ooxml with , tags in places. I've seen "hidden" property in the preview word api, I even tested it, but it left the content control itself (and section title) visible for some reason. I need a solution that I can use now.

@shanshanzheng-dev the same example document has numbering rendering issues in WOPI , uncertain if related, reported here https://github.com/OfficeDev/office-js/issues/4698#issuecomment-2245378359
