Wow, this is great! Thanks for pointing to this new structure in iOS26.

Thank you very much for your reply, and the immediate confirmation that customization of the PDF background color in the new WebView is not (yet) supported. I have filled the report / suggestion under FB18047871.

Thanks @Peiran! Your solution works better than I expected. Though I hope that the** onScrollVisibilityChange** does indeed somehow work with List.

Thanks, even though I accepted the answer, following some further reflection, I wanted to come back to your reply. Whereas the onScrollGeometryChange(for:of:action:) does indeed work with Lists, it does not offer more precise control of the change of visibility of specific views within the list (e.g. sections). Do you have any advice on how to make the onScrollVisibilityChange work for this purpose?

I can confirm. My issue was resolved by reducing the date range.
