Ideas

Use case:

If your customers total cart is above some threshold, e.g. 499, you want to give a 20% discount for the selected order rows.

Current discount calculation:

When using threshold with discount type "Product discount in % or amount off" the evaluation is happening "row by row", so for instance if you have two rows that costs 250 each with a total sum of 500 and then applying your discount. The first row will be discounted, and then the second row is evaluated against your discount rules, now the total sum is below 499, hence - the discount will not be applied to the second row.

Wanted logic:

The threshold should be applied for the cart total only before the rows are being calculated so that all rows gets a discount.
