If you use aria-describedby to associate a tooltip or error message with a grouping element (a <fieldset> element or an element with role="group" or role="radiogroup") you would expect NVDA to read the value of the associated element whenever it reads the legend (or common label) of the group. This, however, is not the case.

Steps to reproduce:

1. Open the attached .html file (it is just a static file, no Javascript or CSS validation).
2. Move focus into the groupin element, (tab from the "Google" link to the "red" checkbox or shift-tab from the "Verify" button to the "Peppermint" checkbox.

Actual behavior:

NVDA announces the label of the checkbox and the common label of the group, "What's your favorite color".

Expected behavior:

NVDA should announce the label of the checkbox, the common label of the group and the associated error message

e.g.
"red, checkbox not checked, What's your favorite color, grouping, error! You must select at least one color"
