Under Linux desktops it is normal to mark any text with the mouse and then insert it anywhere with the center button (wheel) of the mouse.
If you now have the VisualEditor open in Chrome or Chromium and want to insert marked text with the "middle-click-paste" function, the cloud symbol will always appear instead of the text: ☁
Normal copy / paste works as desired.
Under Firefox the problem is not present.
Btw. the problem is also present in THIS editor. ;)
