[Bug] PDF generation fails when TOC has many bookmarks

Describe the bug Hi, I have strange problem with generating PDF when TOC.md contains some links with bookmarks. It works locally on my laptop but when I'm doing the same on Windows Server PDF generation fails.

PDF generation turned off - no error. In generated TOC.html links are working. I've tried TOC.yml instead TOC.md - the same error. Locally on Windows 11 works, but on Windows server - it fails.

To Reproduce Steps to reproduce the behavior:

Create file "article1.md" with following content:

# header1
## header2
### header3-1
### header3-2
### header3-3
### header3-4
### header3-5

Create "TOC.md" with following content:

# [header1](article1.md#header1)
## [header2](article1.md#header2)
### [header3-1](article1.md#header3-1)
### [header3-2](article1.md#header3-2)
### [header3-3](article1.md#header3-3)
### [header3-4](article1.md#header3-4)
### [header3-5](article1.md#header3-5)

Run docfx with pdf generation

docfx.json:

  "build": {
    "content": [
      {
        "files": ["**/*.{md,yml}"],
        "exclude": ["**.*.pdf"]
      }
    ],
    "resource": [
      {
        "files": ["**/media/**"],
        "exclude": ["**/obj/**", "**/includes/**"]
      }
    ],
    "overwrite": [
      {
        "exclude": ["obj/**", "_site/**"]
      }
    ],

      "pdfFileName": "doc-pdf.pdf"
    },
    "globalMetadataFiles": [],
    "fileMetadataFiles": [],

    "noLangKeyword": false,
    "keepFileLink": false,
    "cleanupCacheHistory": false,

Expected behavior PDF should be generated without any errors/warnings.

Context (please complete the following information):

OS: Windows Server 2019, 2022
Docfx version: 2.76.0

Additional context

I noticed - when I remove last line in TOC.md - this one:

### [header3-5](article1.md#header3-5)

Everythings works and there is no error:

XRef map exported.
Extracting index data from 4 html files
Content\doc-pdf.pdf: 0%
Content\doc-pdf.pdf: 53%
Content\doc-pdf.pdf: 99%

Build succeeded.

    0 warning(s)
    0 error(s)

Adding any next link with bookmark causes error but adding link without bookmark works. So it looks like there is some problem above 6 links with bookmarks or maybe there is limitation I don't know. Could someone check this issue or tell me how to resolve/workaround that?
