Entity type menu_link_content is currently not translatable. Implementation required.

If you try to translate a menu_link_content entity, the following exception occurs:

Error: Call to a member function getTargetBundle() on null in Drupal\menu_item_extras\Plugin\Field\FieldWidget\MenuItemExtrasViewModeSelectorSelect->getFromWidgetViewModes() (line 95 of modules/contrib/menu_item_extras/src/Plugin/Field/FieldWidget/MenuItemExtrasViewModeSelectorSelect.php).

A skip list has been created in the operations hook to prevent hard errors.
