Fix this: downloading a .txt file in Teams on a Mac using Safari opened the file in that browser tab instead
While using Office365 Teams via the Safari browser on my Mac computer, I clicked the ellipsis symbol next to a plain ordinary .txt file and then selected the Download option. Instead of downloading the file as it should have done (and as anyone would expect), the .txt file was opened in the same browser tab, replacing the Teams chat i which I had been working.

Clarification: The .txt file had been sent to me as an attachment within the Teams chat by the other person involved.
