Expected Behavior

When opening a workbook with loadWorkbooks, all tabs should retain the same visibility state that they have in the saved workbook that is loaded.

Actual Behavior

All tabs become visible.

Steps to Reproduce the Problem

(please attach an example xlsx file if possible)

1. Create a workbook (an .xlsm in my case, if that matters)

2. Hide one of the tabs

3. call wb <- loadWorkbook(filename)

4. sheetVisibility(wb) will show all the tabs are visible; when saving the resulting workbook, all of the tabs are visible.
