Contact module categories has not support language select

This question is raised in #2289063: Change contact message entity to behave more like a normal entity

having a go

Without a canonical link to view a message (or to edit it like block content uses) content_translation ignores ContactMessages so doesn't create the required permissions and the test dies.

Why is this postponed? Is there another issue we're waiting on?

looks strange

let's add lancode key at least

I forgot about this issue. The language selector actually show up now, the only problem is that it's not configurable, which is fixed by #2533964: Langcode widget visibility settings from language.module are not applied consistently, which also adds the langcode key.
