When a page is delivered through an external translation service some functionality may be missing. Delivering the mobile version for such content (T212197) and adjusting the page actions (T212202), helps to reduce the functionality exposed that won't work on an external service.
In addition to that, the current ticket is intended to review other information and functionality in the page that may not work as expected in order to decide whether to hide it, disable it, or redirect to some wiki page instead. Some of the elements to review include the options provided in the "hamburger" menu, search, page issues, footer menus, and similar.
