Bug description

Hi,

The slider skips a lazy load image in this case; in below example "image04.jpg" is not preloaded but e.g. image05 is preloaded:

looks like "watchSlidesProgress:true" is causing the issue but I need it because of the "right click on link resets slider"-bug: #5814

Regards.

Expected Behavior

lazy images preloaded, respecting loadPrevNextAmount

Actual Behavior

image04 skipped from preloading which results in loading-flicker

Swiper version

8.3.2

Platform/Target and Browser Versions

Swiper v9 doesn't lazy module anymore. If you have similar issues in Swiper 9, open a new issue with a CodeSandbox showing the issue.
