Steps to reproduce the problem:
Using the NVDA screen reader:
1. Go to GMail and use the keyboard to slect a message in the list.
2. Press numpad 8 to read the current line.
3. Observe nothing is spoken and the screen reader is silent.

What is the expected behavior?
The command should allow NVDA to read the currently selected or focused line.
This does work correctly in Firefox.

It doesn't work.
