This PR fixes how the Mini Cart block loads the translations.

Fixes #6153

Technical details

I guess that the current method of how the Mini Cart block loads the translations is not correct. It seems that all the blocks using the method register_chunk_translations.

@dinhtungdu noticed that the function append_script_and_deps_src is used to lazy load the dependencies of Mini Cart and payment method scripts. Are we sure that the line about the translation is necessary?

Another doubt that I have: what are the advantages to split the handling of the translations compared to the other scripts with the suffix before? (here the code)

Testing

Manual Testing

How to test the changes in this Pull Request:

Check out this branch

  1. Go to Settings -> General and change the language of the site to any language other than English (my suggestion is to use Dutch because all the translations are available).
  2. Enable a classic theme (for example Storefront)
  3. Now go to Appearance -> Widgets and add Mini Cart widget to any Widget Area.
  4. Go to any page containing that Widget Area and check that any error related to wp.i18n.
  5. Check that the Mini Cart is translated (check with an empty cart and with a filled cart). Please, be sure that you are using a language that has translations for the Mini Cart Block. My suggestion is to use the Dutch language.
  6. Enable a block theme (for example TT2).
  7. Now go to Appearance -> Editor and add the Mini Cart block in the header. Save.
  8. Check that the Mini Cart is translated (check with an empty cart and with a filled cart). Please, be sure that you are using a language that has translations for the Mini Cart Block. My suggestion is to use the Dutch language.

Tested with deutsch and all strings are translated 🎉 . However, the translations are included in the server-rendered HTML with this approach. I think we should lazy load the translations instead. #6164 is my idea to lazy load the translations, can you please take a look?

'version' => $script->ver,
'before' => $wp_scripts->print_inline_script( $script->handle, 'before', false ),
'after' => $wp_scripts->print_inline_script( $script->handle, 'after', false ),
'translations' => $wp_scripts->print_translations( $script->handle, false ),

Looking closer, I notice that the $wp_scripts->print_translations() of enqueued scripts cause the JS errors; even we don't echo them, they are still printed.

Not sure if related, but I remember being confused by something similar and it was because we hook into pre_load_script_translations to print the translations, which runs no matter if you echo them or not:

Thanks for investigating this tricky issue, @gigitux and @dinhtungdu! I could verify this PR fixes the issue, and translations are loaded correctly, so I'm pre-approving. Besides that, I left a couple of questions of changes to help me understand the changes.
