Describe the Bug

Currently the document node is rendered as a root node of the tree, but it's basically a duplicate of the header. We should instead render from the root field in case the document is structured (i.e. schema is attached)

Source Body

Body is a root node where the header above also shows Body. We should instead show Cart as a root node

Source Param

In this case since param name (=document name) and the root node are both named Account, it ends up showing Account 3 times

Target Body

Not only Body is a duplicate, but it also duplicates the Attach/Detach schema buttons as well. We should show them only on the header. However once the root node is correctly shown, buttons would also go away.
