Since bug 120891 got fixed, the layout will always be updated by just using a TextIterator (it happens in the constructor), which is used from AccessibilityRenderObject::textUnderElement() when dealing with text objects. This means that calls to that method can potentially alter the accessibility tree and thus other methods relying on this should be considered as non-const.
