            Bug ID: 230687
           Summary: AX: aria-level is no longer supported on grid or
                    tablist in ARIA 1.2
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jdiggs at igalia.com

Steps to reproduce:
1. Load `data:text/html,<div role='grid' aria-level='2'>...</div>`
2. View the element using Accerciser

Expected results: The level of the grid would not be exposed because in ARIA 1.2 aria-level stopped being a supported property on grid and tablist. The spec also states:

> User agents MUST ignore non-global states and properties used on an element without a role supporting the state or property

Actual results: The level is exposed.

It doesn't seem to be exposed in Safari. Also, removing the role completely doesn't stop the exposure. So we're presumably just passing it along all the time in ATK.
