The "Profile" page of the environment provides a series of simulated tab controls that provide pages of content pertaining to the currently signed in profile. These are simply comprised of links that take the user to selected content. However, a <tabindex="0"> attribute has been placed on the <span> inside each of the anchor elements. This results in keyboard focus transferring first the tab control, and then to the visual label inside the control. This can be confusing for keyboard users who will not know the difference between activating the tab control or the visual label.
Developers must ensure that keyboard focus is provided only to the control, and not the textual element inside the control. As such, developers must remove the <tabindex="0"> from the <span>, and rely on the anchor element itself to draw keyboard focus.
