/**
 * Makes sure the unmodified ConfigEntity is loaded on admin pages.
 *
 * Converts entity route arguments to unmodified entities as opposed to
 * converting to entities with overrides, such as the negotiated language.
 *
 * This converter applies only if the path is an admin path, the entity is
 * a config entity, and the "with_config_overrides" element is not set to TRUE
 * on the parameter definition.
 *
 * Due to this converter having a higher weight than the default
 * EntityConverter, every time this applies, it takes over the conversion duty
 * from EntityConverter. As we only allow a single converter per route
 * argument, EntityConverter is ignored when this converter applies.
