The cell values of F3 and F4 aren't read correctly

When reading a string cell value from excel (see attached xslx file) the line break is read as _x000D_.

The code below with the provided excel sheet can be used to reproduce this (3.7 Beta 1)

InputStream xlsInputStream = new FileInputStream(new File(
        "f:\\vfs\\UnReadableStrings.xlsx"));
    Workbook wb = new XSSFWorkbook(OPCPackage.open(xlsInputStream));
    
    Sheet sheet = wb.getSheetAt(wb.getActiveSheetIndex());
    Row row = sheet.getRow(2);
    Cell cell = row.getCell(5);
    System.out.println(cell.getStringCellValue());
    
    row = sheet.getRow(3);
    cell = row.getCell(5);
    System.out.println(cell.getStringCellValue());

Output: 
1行目_x000D_2行目
1行目_x000D_
2行目
