Right now, the accessibility tree is built recursively, and at each layer of the DOM we create a new ComposedTreeIterator. It would be much more efficient to use one ComposedTreeIterator throughout each "build cycle" to traverse all descendants rather than creating a new one at each stack frame. This will likely require some larger changes to how we build the accessibility tree.
