[orca-list] Orca reports blank when navigating google docs document

[Peter Vágner <pvdeejay gmail com>]

Hello,

Can anyone please try to reproduce this?
0) Make sure Orca and Firefox both are running.
1) Go to https://docs.google.com, login with your google account, open a 
document and focus the document area.
2) Use all four arrow keys to navigate the document.

Actual results:
 orca presents live regions Google docs team has implemented in place 
of accessible rich text editor. However immediately just before that it 
attempts to read the content of the control with focus. That control has 
no text thus orca reports blank each time pressing an arrow key while 
this view is in focus.
When pressing ctrl or shift + arrows orca does not say blank here.

Is there a way to filter this out without breaking something else please?

Greetings

Peter
