[CONFIRMED] Coupon System different total amount depending how the product is

Testing Coupon System I got different total amounts depending how the product was added to cart.

Created a coupon value $15 (15 off from total)

Created a product worth $10, added the product to cart, applied the coupon got the following message.

Info: The Value of the Coupon is greater than the current Order Total, so the Coupon Value was temporarily set to $10.00

Cart total is set to 0 zero up until now all is OK.

Now updating quantity of the product to 2 from within the cart sets the total cart value to $5.00 which is correct 10*2=20 - 15 = 5

However instead of updating the product quantity from within the cart going back to product list and adding the same product once more sets the cart total to $10 which is incorrect.

Now the fun part emptying the cart and adding the same product back to the cart sets the cart total to -5 mathematically this is correct 10-15=-5 but for business it's a big No.

Could one of Q&T members check this.
