When I added an Reusable subprocess by quick menu and morph subprocess to another type (Embedded, Event, Ad-Hoc) it is not possible to place any node inside of subprocess. I will see

 Error Command execution failed.<br>Reason/s: <br>[1] (ERROR) Containment operation not allowed<br>

PR Acceptance test

• Add reusable subprocess from palette, morph to other sub process type, try to put node inside, save and reopen
• Add reusable subprocess by context menu of other node, morph to sub process type, try to put node inside, save and reopen
