Gallery component does not render .webp images in Apple News Format

Hi team,


I'm currently implementing a gallery component using Apple News Format and noticed that images using the .webp format are not being rendered inside the gallery.


Here's a working example I tested


{
  "role": "gallery",
  "items": [
    {
      "URL": "https://storage.googleapis.com/skratch-strapi/Getty_Images_2195923330_6b173dfe50/Getty_Images_2195923330_6b173dfe50.jpg",
      "caption": "asdasdas"
    },
    {
      "URL": "https://storage.googleapis.com/skratch-strapi/Callaway_Edge_Set_Costco_ee784c6aa8/Callaway_Edge_Set_Costco_ee784c6aa8.jpg",
      "caption": "adsasasda"
    },
    {
      "URL": "https://storage.googleapis.com/skratch-strapi/Screenshot_2024_11_29_at_2_04_55_PM_9807ba59a9/Screenshot_2024_11_29_at_2_04_55_PM_9807ba59a9.png",
      "caption": null
    },
    {
      "URL": "https://storage.googleapis.com/skratch-strapi/dynapwr_carbon_FW_cf6e057b47/dynapwr_carbon_FW_cf6e057b47.jpg",
      "caption": null
    },
    {
      "URL": "https://storage.googleapis.com/skratch-strapi/23049476_53764287_1000_9f9770965c/23049476_53764287_1000_9f9770965c.webp",
      "caption": null
    }
  ]
}


The .jpg image renders fine, but the .webp image does not show up and causes the following error:


Error: Resource with URI [https://storage.googleapis.com/skratch-strapi/23https://storage.googleapis.com/skratch-strapi/23049476_53764287_1000_9f9770965c/23049476_53764287_1000_9f9770965c.webp]



The same .webp image works perfectly when used as a photo component, so it seems this may be a limitation or bug specifically within the gallery role.


Can you confirm if .webp images are supported for gallery items?


Thanks for your help!
