Indeed, and now the question is which one of these is the faulty one:

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

However, if this fails this way 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, I think I'll file a bug for this test too, and add it to mac/TestExpectations too.
