Resaving views in postupdate writes language overrides

Problem/Motivation

On update to core 8.4, the postupdate code below (run via drush) smashed all my views config, by replacing all strings with a translated version like this:

-      title: 'Monthly archive'
+      title: 'Monatliches Archiv'

It looks like the language overrides get saved.

To reproduce (i guess the language setting is important):
* set english as default language
* set (e.g.) german as default negotiation language
* have a view with translated title
* load and re-save the view

/**
 * Fix table names for revision metadata fields.
 */
function views_post_update_revision_metadata_fields() {
  // The table names are fixed automatically in
  // \Drupal\views\Entity\View::preSave(), so we just need to re-save all views.
  $views = View::loadMultiple();
  array_walk($views, function (View $view) {
    $view->save();
  });
}

Proposed resolution

* Find and crosslink the issue(s) about config override saving
* Check if they fix this OR we must make views leverage this
* Decide what to do with the upgrade path
