1218897 - [Accessibility] Screen reader can not access activity window.

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::System::Window Mgmt, defect)

Description

[Yura Zenevich [:yzen] (please use "needinfo")]

This seems like a regression because we used to access activity windows with the screen reader.

The core issue here is that activity window is rendered inside an app window container that is marked inactive and thus has aria-hidden attribute set to "true".

Steps to reproduced were reported by Julien in https://bugzilla.mozilla.org/show_bug.cgi?id=1211115#c12 

1. Open the Messages app
2. Activate the "new message" button.
3. Activate the "+" button.

=> Then I couldn't select a contact. The whole activity window is not visible to the screen reader.

Gabriele you handled another issue caused by Bug 1144132.  Can you weigh in here as well?

Comment 3

[Gabriele Svelto [:gsvelto]]

This is most likely due to the window management changes which I'm not very familiar with. I only handled the gecko part of bug 1144132 so I'm NI'ing Etienne who certainly knows more.
