saveAs doesn't work in Outlook Desktop Client

This library works well in all browsers including IE11 but refuses to download files in Outlook 2016 Desktop Client on Windows 10. In Outlook 2013 on Windows Server 2008 R2 it is working.
It returns the javascript error:
`SEC7134: Resource 'blob:https://mydomain.herokuapp.com/myfile-guid-acbd-6bdf92b3fab6' not allowed to load.`

The issue started after the latest Windows 10 update - 1903.
Now, as far as I see in Outlook devtools console, the property `navigator.msSaveOrOpenBlob` doesn't exist anymore.
