JAWS narrates wrong instruction message for radiogroup in toolbar

[kolaps33]

Summary

Example:

1. Go to https://www.w3.org/TR/wai-aria-practices-1.1/examples/toolbar/toolbar.html
2. Navigate into the toolbar
3. Use right arrow key until you reach radio button with name "Text Align Left"

Actual result

JAWS narrates instruction message like:
"To change the selection press Up or Down Arrow."

Expected result

JAWS shouldn't narrate instruction message because changing the selection is doable via space/enter key on the item.

[JAWS-test]

In HTML, it is normally the case that radio buttons are selected using the arrow keys, i.e. navigating through the radio button group automatically causes the focused radio button to be activated. In this respect, the JAWS message is correct. In the toolbar example, this is implemented differently: but how should JAWS know that. In my opinion it is an error of the toolbar example of WAI-ARIA.

The only thing JAWS could do here would be to stop outputting an operation note at all, to be open to different radio button implementations

For reference purposes: https://www.w3.org/TR/wai-aria-practices-1.2/#for-radio-group-contained-in-a-toolbar which recommends the interaction for a radio button group contained in a toolbar present in the example linked to. JAWS describes the standard interaction for a radio button group. Perhaps arguably, in unusual cases like this, a description of how to interact with the group should be provided in the HTML?
