Steps to reproduce the problem:
1. Run JAWS.
2. Install any extenssion and run their settings or application page
3. Try to navigate with virtual cursor and you will see that JAWS reads nothing.

What is the expected behavior?
JAWS read before all pages and settings of most extenssions and I expect to it happen again.

What went wrong?
JAWS dont read anymore ssettings or HTML content of extenssions.

Did this work before? Yes Last time in Chrome 50 stable.
