Spreadsheet: Improper copy paste to Excel when merged cells are present and one column in the merged cells range is hidden. If the column containing the first merged cell is hidden all the rows on that row will be shifted to the left.

Reproduction of the problem

• Run the following Dojo;
• Select Range A1:D3 (note that column B is hidden)
• Press Ctrl + C;
• In Excel workbook press Ctrl + P;

Current behaviour

After pasting, the merged cell consists of 4 cells, as expected, but the cell data is shifted to the left and the hidden column contains the cell data of the next column

Expected/desired behavior

The cells after the merged cell should not be shifted.
