           Summary: [MAC] accessibility/loading-iframe-updates-axtree.html
                    is crashing
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mario at webkit.org
                CC: webkit-bug-importer at group.apple.com


accessibility/loading-iframe-updates-axtree.html crashes because of trying to use isEqual() with undefined objects in one of the following statements:

    shouldBeTrue("iframe.isEqual(newIframe)");
    shouldBeFalse("scrollarea.isEqual(newScrollarea)");
    shouldBeFalse("newSubwebarea.isEqual(subwebarea)");

I think that it might be uncovering an issue in the test itself, since it might be that the isEqual() operation that we were doing until now were comparing two AccessibilityUIElements with invalid platformUIElement()'s, which is not what the test is supposed to check:

    description("This tests that if an iframe loads new content
                 after its accessibility object has already been
                 accessed, the iframe accessibility object's
                 descendants are the new scroll area and web
                 area, not the old deleted ones.");

So, now filing this bug and adding it to mac/TestExpectations too
