299342@main switched from using a `data:` url for the images in media control buttons to loading a native image from the file system, creating a `blob:` url, and using that to set an <image> element's src attribute. Images loaded for the default media controls are exempt from CORS checks but they are subject to content blocker rules, so applications that configure the content blocker to disallow `blob:` urls have no images in the default media controls.
