Mimetype "application/vnd.ms-excel.sheet.macroenabled" not recognised after uploading new version
Following an upload of new version of an .xlsm file on Cloud (from any browser), the mimetype is lost.
Subsequently, in IE (only), when downloading the ".xlsm" file that was updated by uploading a new version, the document will be downloaded as a ".bin" extension because the mimetype is "Unknown". Downloading the file from any other browser appears to to keep the extension.
[Steps to reproduce]
1. Login to Alfresco Cloud from any browser
2. Upload the attached ".xlsm" document - check the mimetype and preview (should be fine).
3. Upload a new version (click on 'Upload New Version') - check the mimetype, it will be "Unknown" and preview will not work (please see the screenshot bellow)
4. From IE, click on Download and see the message bellow - check the extension (it will be ".bin")
Updating an existing XLSM file shouldn't break the mimetype recognition, subsequently downloading the file using IE should retain the correct extension.
It seems that the mimetype is not updated properly and causing the issue
[Analysis to date]
1.) Reproducible just on Alfresco Cloud not on Alfresco One on-premise
2.) Screenshots attached
