Fix Dragging Screenshot Preview Window to Drop onto Chat or Channel
On macOS 10.14 or later, when you take a screenshot with any keyboard shortcut, you get a preview window like in the attachment right above the dock near the Trash.
You can't drag the screenshot preview window and drop it into Teams like you can for...any other app like Outlook.

This is working on Teams 1.3.00.362
Yes. This. Now. Literally have to work around this flaw dozens of times a day
