// InternalsAccessibility implements several accessibility-related methods that
// are exposed on the Internals object. These methods are used by various WPTs
// to inspect aspects of the accessibility tree that aren't directly obtainable
// through standard JavaScript APIs.
//
// Two of the methods, getComputedLabel and getComputedRole, are exposed on
// WPT's TestDriver as get_computed_label and get_computed_role [1]. The
// TestDriver methods are hooked up to the implementations on the internals
// object in testdriver-vendor.js [2].
//
// See third_party/blink/web_tests/external/wpt/accname/basic.html [3] for an
// example usage of get_computed_label and get_computed_role.
