// We alias a bunch of chrome.extension APIs to their chrome.runtime
// counterparts.
// NOTE(devlin): This is a very simple alias, in which we just return the
// runtime version from the chrome.runtime object. This is important to note
// for a few reasons:
// - Modifications to the chrome.runtime object will affect the return result
//   here. i.e., if script does chrome.runtime.sendMessage = 'some string',
//   then chrome.extension.sendMessage will also be 'some string'.
// - Events will share listeners. i.e., a listener added to
//   chrome.extension.onMessage will fire from a runtime.onMessage event, and
//   vice versa.
// All of these APIs have been deprecated, and are no longer even documented,
// but still have usage. This is the cheap workaround that JS bindings have been
// using, and, while not robust, it should be secure, so use it native bindings,
// too.
