Bug description

If there are multiple swiper instances on the page, and 1 has a different configuration, it breaks.

Expected Behavior

I can instantiate a Swiper Element with varying configurations/properties through the attribute syntax API

Actual Behavior

In my codesandbox I forked the demo from Examples: https://swiperjs.com/demos#multiple-swipers, and changed pagination to false on the third instance, which causes it to not render.

Swiper version

11.2.8

Platform/Target and Browser Versions

Chrome 136, MaxOS 15.4.1
