The problem is that FlowDocument is a visual element, so if you take
bits of it and put them in another visual element then they aren't going
to be shown in the other one.
IronPython does a lot to make .NET collections behave as Python
collections (you can use the in operator, the del operator etc), but it
doesn't change their fundamental behavior.
All the best,
