When moving a directory A into a directory B which already has a subdirectory named A, Cyberduck prompts whether I want to overwrite the subdirectory and if I confirm, it errors saying it cannot delete directory A: https://i.imgur.com/jCeSykk.mp4

This error is independent on whether there are files in the directory or not. It also does not seem to be a permission error, because trying to perform a deletion through Cyberduck works fine.

The behavior I'd expect is that Cyberduck attempts to merge the two directories instead, and only asks for overwriting specifically for colliding files. It's unclear what exactly Cyberduck is attempting to do instead right now, but in the end no action is taken and it only shows the above error.
