"Upload with temporary filename > Rename existing" always fails with Error: "No such file"

[webhype]

Describe the bug
"Upload with temporary filename > Rename existing" always fails with Error: "No such file"

To Reproduce
Steps to reproduce the behavior:

1. Go to Preferences > Transfers > Upload with temporary filename > Rename existing
2. Drag and drop a random file whose name already exists on the server, so as to initiate a transfer to the SFTP server.
3. Note that the file on the server is not busy, in use, or otherwise "locked".
4. An error dialog appears Error: "No such file"

Expected behavior
I expected the file to be renamed before the upload, so as the existing file be preserved, and the new file take its place.

Screenshots
N/A

Desktop (please complete the following information):

• OS: Mac OS 10.14.6 Mojave
• Version 8.3.3 (37544)

Log Files

Notes
1. It is very possible to rename the file via CyberDuck "manually", and then to initiate the upload, thus removing the name collision. However, I expected the process of renaming-then-uploading to be fully automatic.
2. Clicking "Try Again" when prompted by the error dialog seems to do nothing. Expected would be that it try again and fail again, and so on. It is not clear to me why it fails silently after clicking "Try Again".
