           Summary: JS objects returned by AccessibilityController are not
                    cached, breaks layout tests
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: klinktech at gmail.com


The accessible objects returned for DOM objects on the page are not cached; so,
if you try to use JavaScript to get the accessible object for the same element
on a page twice, it will return different values each time. This makes a
comparison of the objects fail, both on Mac and Windows.

Attached example layout test fails as:

FAIL accessibleForID('body').parentElement() should be [object
AccessibilityUIElement]. Was [object AccessibilityUIElement].
FAIL accessibleForID('parent').parentElement() should be [object
AccessibilityUIElement]. Was [object AccessibilityUIElement].
FAIL accessibleForID('child').parentElement() should be [object
AccessibilityUIElement]. Was [object AccessibilityUIElement].
