The getStructTree builds up the tree starting from content refs.
If a struct node (such as a TD) does not include a content, no StructElementNode is created for that branch.

I don't know if this is actually a bug or the intended behavior. If you don't consider it a bug, would you accept a PR that modifies this behavior via a property to get the full tree?
