Swiper inside modal

Not sure if this should work, but it allows me to add everything through the App Structure so I assume it should.

If I place a swiper component with static slides inside the body of a modal component, then the swiper stops working, although if i take it out the modal it works perfectly.

Modal is inside a Partial, which is inside a Page, and the Page is inside a Layout, if that makes any difference.
