In normal circumstances, a radio button set only has one tab stop. Users can tab to the radio buttons, use their arrow keys to navigate between radio buttons, and tab away from the radio set. When a radio button form field exists inside a pop-over component, every radio button is included in the tab order of the focus trap inside of the pop-over. This requires keyboard users to press the tab key more times than normal.
