Both dynamic snippets and visible on mobile use the `d-none` class:
- dynamic snippets activate it by default and only remove it when the
content is ready to be displayed
- visible on mobile makes the section `d-none` when it must be hidden on
mobile and the class is contradicted by another class which is only
taken into account non-mobile
This commit introduces a dedicated class to temporarily hide the dynamic
snippets.
