Bug#833784: nautilus progress bar popup gets own window with decoration

[darthead]

Package: nautilus
Version: 3.20.1-3
Severity: normal

Dear Maintainer,

I'm experiencing weird behaviour with nautilus (3.20.1 on debian
testing/gnome3, everything up to date):
When there is an ongoing filesystem operation such as copying or moving a file,
which is displayed in the circle-diagram left of the search lens, and I then
close and reopen nautilus (just closing the window, which does preserve the
task in the background), the progress bar(s) appear with the new window opening
and get their own window with decoration, and the location is also completely
off (as it should usually be right under the circle diagram when clicking on
it).

On my machine, this behaviour has been reproducable after a reboot.
