 // FrameHost is the set of global data shared between multiple frames
 // and is provided by the embedder to each frame when created.
 // FrameHost currently corresponds to the Page object in core/page
 // however the concept of a Page is moving up out of Blink.
 // In an out-of-process iframe world, a single Page may have
 // multiple frames in different process, thus Page becomes a
 // browser-level concept and Blink core/ only knows about its LocalFrame (and
 // FrameHost).  Separating Page from the rest of core/ through this indirection
 // allows us to slowly refactor Page without breaking the rest of core.
 // TODO(sashab): Merge FrameHost back into Page. crbug.com/688614
