AFAIK, this has been a problem in 2019 version as well.
Pain threshold just happened to be exceeded in this version.
Can be easily reproduced.
1. Create empty file (new_file)
2. Attempt to save file (Cmd-s)
-> "Save As" edit field contains "Untitled"
3. Enter forward slash in Save As edit field.
->This raises the "Go to the folder:" dialog
5. Try Copy/Paste operations in edit field
-> Copy paste not possible - only hear error bell
Thanks in advance!
