Ubuntu 16.10. I just noticed a new behaviour, and I'm wondering when/why this has changed.
before: when dragging a file/folder onto another folder icon, the target folder used to open to display its contents, at which point you could release the original file/folder wherever you'd like.
now: when dragging a file/folder onto another folder icon, the target folder now just changes its icon to a partially open folder icon.
When/why did that change? Is the "before" behaviour from 16.04?"
