That's where I think this behavior is wrong. this shoud just set the
direction to be used internally, hiding this detail to the outside.
Both sequences should behave like if this was a single character with
weak Bidi class. Otherwise they are not really "embedding". Even the
name "pop directional format" is misleading in this case because it
actually does not restore the state that was before the state pushed
