[orca-list] Orca doesn't seem to be returning to browse mode when the focus was on a read-only field

[José Vilmar Estácio de Souza <vilmar informal com br>]

Hi all.

To reproduce try the following steps using the latest orca from master 
because it doesn't happen with orca 3.36.1


1. Using FF access the following url:

https://hub.docker.com/_/php-zendserver


2. After the page is loaded press tab until you find a read only field 
with the following description:

Copy and paste to pull this image

Note that the orca switches to focus mode as expected.

3. Press tab.

The orca should switch to browse mode but at least in my environment it 
doesn't.


Works ok with orca 3.36.1
