  // To avoid unintentional reverts and data losses, we forbid changes to
  // untranslatable fields in pending revisions for multilingual entities. The
  // only case where changes in pending revisions are acceptable is when
  // untranslatable fields affect only the default translation, in which case
  // a pending revision contains only one affected translation. Even in this
  // case, multiple translations would be affected in a single revision, if we
  // allowed changes to untranslatable fields while editing non-default
  // translations, so that is forbidden too. For the same reason, when changes
  // to untranslatable fields affect all translations, we can only allow them
  // in default revisions.
