Steps: 1. Go to the URL. 2. Start editing the page using the VisualEditor. 3. Move the cursor using the keyboard arrow keys forward (right). Observed: When you get to the "Done" template and go on moving the cursor, the whole template disappears. The same happens when you get to the reference number on the second line ("[1]"). The cursor must probably skip over them and definitely not make them disappear.
I have a good reason to believe that this occurs only in Firefox and I just fixed it here: https://gerrit.wikimedia.org/r/#/c/61055/. If you get it in other browser then pelase reopen this bug.
And actually the desired behavior is not skipping over - it is selecting it (so you can delete if you want) - give it a try in Chrome.
