Fix diagram copy-paste regression
The changes done in redmine platform issue 7728 back in March 2018, i.e. commit b9b77f42 had seriously bad effects on how e.g. diagram copy-pasting performs, at least in Apros.
It is highly likely that also other products are affected. This should be fixed from 1.34.0 before it is tagged and used in products.
See Apros issue 14162 as well.
