Unable to reference AB test email in smart list or campaign

After creating an Email Program with an A/B test, you create smart lists (or smart campaigns) and would like to use filters such as "Opened Email" for the A/B test email.

When starting to type the A/B test email name into the smart list filter, the A/B test email name does not show as available to select (it may show a red squiggly line).

The Email Program (with the A/B test) needs to be in "Approved" status before the A/B test email assets can be entered into a smart list filter.
