Bug description

It seems while in the browser the swiper-slide-active class is set and switches everytime a swipe happened, this bevahiour is not reproducable within a unit test.

My intention is to test if a function was triggered on a slide-change, but since the swiper-slide-active class is not even set in the jsDOM environment, it seems that the swiper is not even properly initiated.

Expected Behavior

The expected behaviour is, that the active class swiper-slide-active is also set when rendering the swiper within a unit test, using jest/react.

Actual Behavior

The swiper-slide-active is never set, which is an indicator, that the swiper container is never properly initiated.

See provided sandbox environment.

Unfurtunately the only workaround for this is skip the test 🤦🏻‍♂️

Sorry to say this. Is unfurtunate, that noone is reacting to this
