to workspaces in Mantid are now synchronised with MSlice for shared workspaces. For example, this change now ensures that a deleted workspace in Mantid is also deleted in MSlice, which mitigates a common past error of `RuntimeError: Variable invalidated, data
has been deleted`. The behaviour of the MSlice interface is thereby made consistent with that of other interfaces.<o:p></o:p></span></p>
