I am going to assign the "Core: Layout: Images, Video, and HTML Frames" component for it.
Component: Untriaged → Layout: Images, Video, and HTML Frames
Product: Firefox → Core
Preloading is DOM code, technically, I guess.
Status: UNCONFIRMED → NEW
Component: Layout: Images, Video, and HTML Frames → DOM: Core & HTML
Ever confirmed: true

rel=preload is not implemented yet. This needs to wait...
