This tests that native elements and ARIA overrides result in the same ARIA computed role, regardless of platform.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

        The display property of many MathML elements can not be overriden by page authors

        https://bugs.webkit.org/show_bug.cgi?id=139403

        The mathml.css user agent stylesheet currently forces most MathML elements to render with

        'display: block'. We remove the !important property so that users can override the display

        property, for example to hide elements with 'display: none'. This is consistent with the

        behavior for SVG or HTML elements.
