Bug description

Swiper 9.0.2 + React 18.2.0 in StrictMode

If you set loading='lazy' to image element inside SwiperSlide and set React.StrictMode you will see error message

Uncaught TypeError: Cannot read properties of undefined (reading 'slideClass')
    at slideSelector (process-lazy-preloader.js:2:1)
    at processLazyPreloader (process-lazy-preloader.js:3:1)
    at HTMLImageElement.<anonymous> (core.js:484:1)

I know that lazy loading reimplemented in Swiper 9.

Is it possible to avoid execution of processLazyPreloader if developer don't want to use preloader spinners?

Expected Behavior

Native lazy loading working without issues in console in React.StrictMode

Actual Behavior

Errors in console:

Uncaught TypeError: Cannot read properties of undefined (reading 'slideClass')
    at slideSelector (process-lazy-preloader.js:2:1)
    at processLazyPreloader (process-lazy-preloader.js:3:1)
