This is a reproduction of an issue with the ion-activatable class and the swiper library.
When using the ion-activatable class on an element inside a swiper-slide element, the "ion-activated" class is added to the element only on touch devices.
Adding the swiper-no-swiping class to the element with the ion-activatable class fixes the issue. However, it blocks the swipe gesture on the element, so it is not possible to swipe to another slide by swiping on the element.
