move sheet to other document in calc preserving named cells

Is it possible to move (or copy) sheets from one calc document to another without loosing named cells (and named areas)?

When I move a sheet from one calc document to another all named cells on that sheet loose their name in the target document.

LO 4.2.8.2 (ubuntu 14.04)

Tested with sheet scope and document scope for named cells and seems to move and copy sheets correctly in LO 5.2.0.4, x64, Windows 8.1.

Can you try a later version? 4.2.8.2 may be quite old now.
