Tooltip not mobile friendly

We have recently enabled the Product Addons on our site, including the tooltip textfield. Since it is an ALT txt over the tooptip image, this isn’t very mobile friendly. It doesn’t even get displayed on a mobile device.

A large percentage of our customers are using a mobile device rather than a desktop computer. I can imagine that a large number of Booster users would benefit from a better solution, ideally without redirecting the customer away from the product page.
