Shopify mobile problem

I am trying to put Shopify in Sparkle to test if it works correctly, and when I embed a button on the sparkle website and in the mobile version I select a color or a size for example, the whole website zooms in and the cart gets cut. Is there any way to disable zoom on mobile or something like that?

An example of what is happening:

Thanks in advance.

Safari zooms in for text inputs that are less than 16 pixels, but this is an issue on Shopify’s end I’d say.
