When one edits a page with a {{Coor}} template on Dutch Wikipedia (nlwp), the geographical coordinate shown in the righthand top corner of the page is drawn twice. One in the original spot and one in the visual editor area. The width of the two 'widgets' seems to be identical but they are otherwise styled differently.
I am not entirely sure whether this is a VisualEditor/Parsoid bug, but it appears whenever one edits a page with the {{Coor}} template on nlwp. I have not tried this on any other wikipedias.

The issue occurs with other browsers and operating systems as well, I have been told.
