Chrome downloads all preload variants

Hello, please check out the configuration guide for this module. Specifically https://www.drupal.org/docs/contributed-modules/responsive-image-preload... →

Let me know how that goes for you 🙂.

One improvement that I could see is having a hook_requirements implementation that checks for misconfigured breakpoints that overlap.

I don't have the bandwidth to add that feature at this time though, unfortunately.

Please feel free to re-open if you are still experiencing issues after going through the docs :-).
