I would say 95% of the time, the aria-owns appear properly. I was not able to reproduce this by opening the pdf manually. Could this issue be due to playwright opening the pdf?

Configuration:

• Web browser and its version: Chromium
• PDF.js version: 3.11.174
• Using react-pdf library

Steps to reproduce the problem:

1. Make a playwright test to open the pdf and to check the aria-owns in the text layer

What is the expected behavior? (add screenshot)
aria-owns appear properly

What went wrong? (add screenshot)
aria-owns does not appear
