Bug reproduction: NodeImporterWithEmptyTextBox.zip (116.9 KB)
When using NodeImporter to import a document into another one (as described here), if the source document has a linked textbox in it, the result is corrupted it seems.
In the attached reproduction, I have three variants of the source document with a red rectangle and a two textboxes, sometimes the two textboxes are linked together.The result of the merge is completely different (i.e. broken) when using the one with the linked textboxes.
Tested with v21.5.0
