New Post: XLWorkbook.Save causes spreadsheet to lose data

I have a similar, yet simpler issue.
I have an existing .xlsx file, setup up with a page-break view. When the spreadsheet is opened and saved, the page-break view is stripped.
The problem is, that the value is never loaded into memory from the original document.
Example:
Original document:
<worksheet .....>

<dimension ..../>
<sheetViews>
    <sheetView tabSelected="1" __view="pageBreakPreview"__ zoomScaleNormal="100" zoomScaleSheetLayoutView="100" workbookViewId="0">

...
...

Calling the following, very simple code on the file, will strip the view-attribute of the OpenXml-file:

    public void OpenCloseWorkbook(string fileName, string sheetName)
    {
        var workbook = new XLWorkbook(fileName);
        workbook.Save();
    }

...

<sheetView tabSelected="1" zoomScaleNormal="100" zoomScaleSheetLayoutView="100" workbookViewId="0">

...


Its a bit annoying that a simple open/close operation modifies the file, but the workaround in my case was simple. I always want a specific value, not nessesarily the one defined in the original document. Therefore I just set it before saving, like this:
workbook.Worksheets.First().SheetView.View = XLSheetViewOptions.PageBreakPreview;
