[orca-list] Accessibility of the GtkListBox container ?

[Alex ARNAUD <alexarnaud hypra fr>]

Dear orca maintainers,

Environment :
- Debian testing (GTK 3.22, AT-SPI 2.22)
- Orca 3.22.2

I'm using and testing the Oomox (theme configurator tool) with both 
screen magnifier and screen reader.

To display the list of theme options it uses the widget "GtkListBox" and 
I see "list item" and "list box" events from accerciser. This widget 
provides the ability to switch between lines with up/down arrow but if 
the blind user doesn't know he is in a list he couldn't use this 
accelerator.
Should Orca announce the entry inside the list ?

You could find a debug log when I enter inside the list and when I move 
between the first and second line of the list :
