Why can I not hide the 'Compare at' prices when discounts are enabled?

When discounts are enabled, the 'Show compare at price' option has no effect:

because when discounts are enabled, 'Compare at' prices are always displayed.

This is done to show the customer the prices before and after applying the discount.

For example, take a look at the following bundle with:

If you take a look at the sale prices in red, they are $39.99 and $18.99 what makes a total of $58.98 but, when we apply the 15% discount, the final price is $50.13.

As the percentage discount is enabled, the original prices have to be displayed to show the price before and after the discount. This is why the app does not have the option to hide the 'Compare at' prices when discounts are enabled.
