/**
* Returns boolean indicating whether the given element has a role
* that is associated with a non-interactive component. Non-interactive roles
* include `listitem`, `article`, or `dialog`. These are roles that indicate
* for the most part containers.
*
* Elements with these roles should not respond or handle user interactions.
* For example, an `onClick` handler should not be assigned to an element with
* the role `listitem`. An element inside the `listitem`, like a button or a
* link, should handle the click.
*
* This utility returns true for elements that are assigned a non-interactive
* role. It will return false for elements that do not have a role. So whereas
* a `div` might be considered non-interactive, for the purpose of this utility,
* it is considered neither interactive nor non-interactive -- a determination
* cannot be made in this case and false is returned.
