Description from GitHub bug:

Configuration:

* Web browser and its version: ALL

* Operating system and its version: ALL

* PDF.js version: Last

Steps to reproduce the problem:

1. Screen reader users do not reach the selected and activated document locations by inner-document link activation or by opening pop-ups.

Set tabindex="0" (the only necessary direct use of tabindex attribute) on the element with the role=main. After the complete document is loaded, set keyboard focus on this position using focus().

User actions in the Table of Contents or on other in-document links should not only scroll the choosen contents into view, but also set the keyboard focus to the activated document location. Only this wya will a screen reader user be in position to get the selected document location.
