curiosity: dropbox cloud icon in tray

Hi all,
today I booted up a remote openSUSE Tumbleweed vm that has been powered off for quite some time.
Initially I used it through ssh only, just to update it. Then I connected to it using Nomachine NX and logged into a graphical session (plasma 5).
I was very surprised to see a little cloud icon in the tray, with a sync indicator. After further inspection I saw it actually was the dropbox tray icon.
I have two other openSUSE Tumbleweed PCs I use and update regularly, and they both have dropbox installed. All three have the same dropbox release.
However, the other two PCs have the traditional dropbox “opened box” icon in the tray.

Trying to understand the reason of the cloud icon, I looked in the .dropbox-dist directory to see if I could find the images for that icon. I found them in the

~/.dropbox-dist/dropbox-lnx.x86_64-23.4.18/images/hicolor/16x16/status

directory. But on all three machines that directory contains the traditional “opened box” icons.

Does anybody else see the cloud tray icon for dropbox? Where does it come from?

Thank you in advance.
Cris

It should be from plasma5 packages. Not sure where it is exactly though.
