I’m building a store with the WooCommerce Block Checkout in Finnish. The coupon input field displays a placeholder text “Enter code”, but there is currently no way to translate it — it doesn't respond to Loco Translate, Say What?, or custom JavaScript.
This causes a mismatch in language on the checkout page. It would be very helpful to allow this placeholder text to be translatable via gettext, or at least configurable via a filter.
