Outline items are not opened/closed correctly

[JanSlabon]

Attach (recommended) or Link to PDF file here: outline.pdf

Configuration:

• Web browser and its version: Firefox (83.0)
• Operating system and its version: Win 10 Pro
• PDF.js version: 2.7.345
• Is a browser extension: no (but should be independent)

Steps to reproduce the problem:

1. Open the PDF in PDF.js Viewer
2. Open the bookmark outline

What is the expected behavior?

What went wrong?

C.A should be closed.

For me it looks like an issue which is caused only if the node that should be closed indcludes "open" nodes. This looks like a wrong interpretation of the /Count entry in outline items.

Link to a viewer (if hosted on a site other than mozilla.github.io/pdf.js or as Firefox/Chrome extension):
