After [1] moved the website edition in the backend, we feel that the code required to make the additional debug icon in the footer of the frontend still work is not worth it. Before this commit, on a website page, it was not working: clicking on it from the WebsitePreview client action would only remove the debug mode of the frontend, and the backend would keep it. The user can now leave the debug mode from the debug menu systray item and we consider that leaving debug mode as a visitor (from the frontend) is not a feature worth keeping.
