Configuration:

• Web browser and its version: Safari, Chrome
• Operating system and its version: MacOS
• PDF.js version: 3.11.174 https://github.com/mozilla/pdf.js/releases/tag/v3.11.174
• Is a browser extension: No

Steps to reproduce the problem:

1. I've modified the method _getVisiblePages() to make render some pages first for ScrollMode.Page
2. But on Browser it always shows 1 visible page only

For example:
When It displays page 1 then load more pages first and make visible on HTML: 2,3

What is the expected behavior? (add screenshot)

Display some pages first

In other words is it possible to get the next or previous page content of the current page?? 🤔
