I have updated the accessibility extension to display all WAI-ARIA properties.
Author: Gez Lemon
I've added a function to the toolbar to display all ARIA roles and properties defined in a document. The properties are displayed in a new tab, along with the value of the property, the element the role is defined on, the parent nodes, and the markup fragment. The following is example output from running the function.
The properties functionality is a catch-all to report all ARIA properties. The toolbar can highlight live regions, document landmark roles, and general roles individually.
