What are you trying to accomplish
Whenever I am trying to create a new page via template, a Builderblock would show up at the bottom of the page, and this is a 0 by 0 empty pixel. This shows up in our production and also local. The empty pixel blocks our interaction to edit, add or remove content on the page.

the empty pixel is not in our codebase.
