Disable Page Scrolling When Selecting Product Size

I am using the Simple layout for product pages and have a string of product images displaying vertically. When I select a product variant (size), the page scrolls to the top. 

Is there a way to disable this page scrolling?

@tuanphan do you happen to have a fix for this?
