Upsell descriptions don't work

Under "monetization" when we're creating products and we're putting in a description for the product, we're not able to add links or images into the description of the product. Why not?

Since this is the "Offer page" we should be able to add rich text here, such as links and images, otherwise, we can't actually get buy-in for members to upgrade. This is a missing feature. PLEASE. And thank you!
