Use GetExtensionOrAppByURL - the URL here is not necessarily a chrome-extension
URL, correct?

Done.

Normally this is sent by
ChromeRenderViewHostObserver::InitRenderViewForExtensions. Does that not get
called for <webview>s?

ChromeRenderViewHostObserver::GetExtension() returns NULL there for guests.

We don't have access to the embedder WebContents in
ChromeRenderViewHostObserver.
