Composite copy structure
vtkCompositeDataSet::CopyStructure would not copy data-information and other meta-data. Since CopyStructure is often used in executive and other filters in place of shallow-copy where leaf datasets are to be shallow-copied, this causes meta-data like time to be dropped. This was manifesting as paraview/paraview#20052 (closed).
Fixed that.
