Ajax add to cart is not working on single page product the same way as shop page
I want to know if this is something that should work on Biolife theme or is out of its scope.
When I have ajax add to cart activate on shop page, after clicking add_to_cart_button, there is a loading icon that displays with add_to_cart_button loading and it stops when the class change to add_to_cart_button added, I really like that and its great for customers to know the system is performing an action to add their products.
Now in single product page, when I have ajax add to cart activate, after clicking add to cart it stops for around 2-4 secs, and after that there is a confirmation, would be great if the same loading icon appears, for user experience is better when any action have a response, I have tried this button with some clients and they get confused by not seeing the loading icon after clicking, because they don't know if their product is actually being added or not. In this case when the class change from "single_add_to_cart_button alt" to "single_add_to_cart_button alt loading" it doesn't show loading icon.
