I was adding a calendar event on Teams (or was it "JS"-Outlook). I wanted to copy from another area in the app, but since it was a modal dialog, I couldn't. There's a button to pop up the "add event" dialog to be its own window. I clicked it, the add event window is now detached. But if course all the stuff I previously entered disappeared, what did I expect, that someone would bother to add code to prevent them from disappearing!?!
