Summary: When expanding one tree, the other tree also expands. This expanding jumps over fragments (which are not in the accessibility tree) so that the trees can stay in sync even when there are extra wrappers in the main tree. Need to figure out functionality for litho components (these simply don't expand together right now since the relationship between the trees at these nodes are less obvious).
