The code that does the transformation can be found in web_contents_adapter.cpp, function fromJSValue():

http://code.woboq.org/qt5/qtwebengine/src/core/web_contents_adapter.cpp.html

Not sure how the JS representation of your tree is.

A possible workaround might be to serialize the data structures, and return a JSON string (e.g. by using JSON.stringify()).
