----------------------------+-----------------------------
 There are various accessibility issues with the collapsable/expandable
 panels in the admin. This panels can be found on the dashboard and in edit
 screens for posts/pages/etc:
  * The collapse/expand is clickable, but has no semantic meaning
  * The clickable element to expand/collapse a panel is not keyboard
 focusable

 Suggested fixes:
  * Use an a or button element, or apply an appropriate aria role (however,
 using of a native element is preferable here)
  * If using an ARIA role, ensure to add tabindex to make it focusable
  * Use the aria-expanded attribute to present the collapsed/expanded
 status of the panel
