Is protection working in 3.0.3?
*Created originally on Bitbucket by [Tim Richardson](https://bitbucket.org/%7B6c0005a9-fb50-47aa-a0e2-b9a93abfe090%7D/)* I can’t get any form of protection working This: ‌ ```python ws.protection.sheet = True ws.protection.password = '123456' ``` does nothing. There are no restrictions on the user. I also tried workbook protection and protecting the structure. When I re-open the spreadsheet, the hashed version of the workbook password is present, but there is no actual protection of the structure. I am opening in both LibreOffice 6.3 and Excel 2016. Is this a known issue?
