Cells.copyRows with conditional formatting in cells causes resulting file size grow in Aspose Cells 8


in Excel document we have to copy cells with conditional formatting. Method Cells.copyRows degrades performance and multiplies resulting file size in Aspose 8. With Aspose 7 it worked fine. Also, it happens only when we copy same row multiple times, but if we will copy, say, row 1 to row 2, than row 2 to row 3 performance and size are ok. Attached is sample to reproduce the issue.

test.xltx is source file with conditional formatting in cells A1-J1
test-aspose-cells-7.7.2.xlsx is file generated with Aspose 7.7.2
test-aspose-cells-8.4.2.xlsx - generated with Aspose 8.4.2
main.java is sample code
