[BUG] Cannot paste into root document tag value node and copy doesn't work

v8.3.3

There is no "Paste" option to paste a structure into the root node of a document tag value, which is quite annoying.. I will need to write this via script.

Also, the "Copy" action doesn't work. It seems to copy the tag path to the tag, not the root node value... looks like i'll need to write more script
