Shown untranslated menu items bug

Is this patch still working in Drupal 9.5.x? When I apply it, I get the following error:

Error: Call to undefined method Drupal\menu_link_content\Plugin\Menu\MenuLinkContent::hasTranslation() in template_preprocess_tb_megamenu_item() (line 687 of modules/contrib/tb_megamenu/tb_megamenu.module).

I modified the patch a bit to get this working:

• Fetch the entity before checking the translation
• Check against the content language (should match the menu items in general) and not the current language

I had to patch it for 3.x branch, here's the patch.

The changes in 🐛 Untranslated menu items are displayed in menus Needs work seem like a cleaner solution. Adding a patch that is based on it.
