Hi Peter.
Your Riot dialogs are now being presented to me. Could you please pull
master and let me know?
Thanks!

Hello,
Excuse me for the delay it took me a bit longer to test this and try to
again find something new within my little project.
The good news is that after you have added this hackaround to orca many
more dialogs are now presented. e.g. the one Nolan has pointed to is
working no mather how many times it shows up. The dialog I have
described at the aria best practices site is also working great now.
Even gnome native dialogs do correctly report the description now e.g.
when trying to connect to a wifi network and there are no known networks
in range.
So overall I think this is a great change.
That last example which is react-aria-modal turned out not to be fully
accessible. It's missing aria-describedby on the dialog node so I should
have checked better before mentioning it.
I still can't get the dialog I'm working on to become accessible.
Please can you take a look at it as I really can't find out what I might
be missing.
With NVDA on windows this is working.
My dialog can be seen at
https://chat.pvagner.tk
There is a row of 6 buttons in the complementary content on the bottom
left I think. These are Home, Start chat, Room directory, Create room,
Communities and Settings. I have added a dummy question dialog to all
these 6 buttons so while testing you don't need to login, or type into
the chat app in question. It's enough t press one of these buttons to
see the dialog in action.
despite adding aria-hidden to the app node, trapping the keyboard within
my dialog, correctly setting up aria-describedby and aria-labelledby I
can't make it work with orca.
Thanks and greetings
Peter

Hey Peter.
I just added a hackaround to Orca master for the issue in which Nolan's
example case isn't fully presented subsequent times the dialog appears.
I am hoping that it also solves your other problems. I'll try to look at
them this weekend -- unless I don't have to because they are solved.
<smile> Mind re-testing?
On a different note, something else wrong with Firefox's JavaScript
