StandardProcessGroupSynchronizer mishandles moving of output ports from one group to another

StandardProcessGroupSynchronizer.updateConnectionDestinations

does not handle output ports that have been moved from one process group to another while kept connected.

The method checks connections and only recognizes if the destination component have been deleted or replaced.
However the outport can also be moved to a child process group.
The method does not recongize this properly and tries to delete the connection while still being connected to the output port which results in an exception
