Configuration:

• Web browser and its version: Safari / 14.0.3
• Operating system and its version: BigSur
• PDF.js version: Latest
• Is a browser extension: No

Steps to reproduce the problem:

1. Navigate to the demo link - https://mozilla.github.io/pdf.js/web/viewer.html
2. Click on print
3. The print renders the exact 14 pages
4. Cancel the operation and click on print for the second time
5. A pop-up comes up asking your permission to print/ cancel
6. Click on print, rather than showing the 14 pages it shows 3 blank pages.

I am trying to skin on top of the default viewer and our team supports safari browser while implementation we came across this issue. I observed that during the second time when the pop-up is displayed the "data-pdfjsprinting" attribute is getting destroyed and it is unable to render the pages as expected.

What is the expected behavior? (add screenshot)
It should show the exact 14 pages as it did for the first time

What went wrong? (add screenshot)

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

Duplicate of #7597, since this issue looks similar enough.

Please note that the web platform unfortunately has quite limited support for controlling printing, and that Safari isn't the main focus of development in the PDF.js library.

@Snuffleupagus, I think the issue I raised looks similar to #9578.
