[alena-marchenko]

Preconditions

1. Magento is installed from 2.2-develop branch
2. Default or Developer mode
3. 2 custom Store Views created and enabled
4. All indexers are valid
5. Different locales are set for each Store View, for example:

• Ukrainian (Ukraine) for the 1st custom Store View
• French (France) for the 2nd custom Store View
• Leave English (United States) on Default Config level to be extended as a locale for Default Store View

6. Magento Cache is flushed if there is a need
7. Product visible for all Store Views is created
8. Put attached CSV files to Magento root folder
   source_fr_FR.csv.zip
   source_uk_UA.csv.zip
9. Run following in console:

• bin/magento i18n:pack --mode=replace -d source_uk_UA.csv uk_UA
• bin/magento i18n:pack --mode=replace -d source_fr_FR.csv fr_FR
• bin/magento setup:static-content:deploy en_US uk_UA fr_FR -f
• bin/magento setup:di:compile
• bin/magento deploy:mode:set production -s

Steps to reproduce

1. Go to Storefront
2. Switch to Storeview with French locale
3. Open product page
4. Click Ajouter au panier to add the product to cart

Expected result

Button changes to Ajout... while the ajax request is processing
When the ajax requests is finished, the button changes to Ajouté
After a bit of time, the button changes back to Ajouter au panier

Actual result

Default string Adding... appears instead of Ajout...
Default string Added appears instead of Ajouté

See #8508 (I managed to resolve similar issue there with code left in comments) and #10673

I believe it's already described as MAGETOTWO-72301 and there's already fix for the problem developed in fc34d7b

This bug is not reproduced following this steps.
But the system has another bug with translations.
It is a wrong translated string(s) for "fr_FR" locale.

Expected result:
Button changes to "En cours d'ajout..." while the ajax request is processing
When the ajax requests is finished, the button changes to "Produit ajouté"
After a bit of time, the button changes back to "Ajouter au panier"

Actual result:
Wrong translated string "Ajouter vos mots clés :" appears instead of "Produit ajouté"
Translated strings for "uk_UA" locale are correct.
