Elements with aria-hidden: "false" are not read when display: none is set

[GoogleCodeExporter]

Per http://www.w3.org/TR/wai-aria/states_and_properties#aria-hidden 

> At the time of this writing, aria-hidden="false" is known to work 
inconsistently when used in conjunction with (display: none). As future 
implementations improve...

Chromevox is one of the implementations that needs to improve.

What steps will reproduce the problem?
1. Hide an element visually with display: none
2. Explicitly ask for the element to be presented to a11y users with 
aria-hidden="false"

What is the expected output?
ChromeVox should read out the element.

What do you see instead?
ChromeVox reads nothing.

What version of the product are you using? On what operating system?
ChromeVox 40.0.2178.0 on OS X 10.10
