Cart badge does not increment on the first add-to-cart click

[satvik007]

Summary

The cart badge should update immediately after the first Add to cart click, but the seeded results record a first-click badge miss.

Observed

Clicking Add to cart for Cappuccino leaves the cart badge unchanged on the first click in the seeded smoke and Chrome cross-browser runs.

Expected

After adding one item, the cart badge increments to 1. Additional items should continue to update the badge as the sum of all quantities.

Seeded coverage

• Add a menu item to the cart (category=Drinks, item_title=Cappuccino)
• Add-to-cart increments the badge by total quantity
