// content's implementation of the BrowserInterfaceBroker interface that binds
// interfaces requested by the renderer. Every execution context type (frame,
// worker etc) owns an instance and registers appropriate handlers, called
// "binders" (see internal::PopulateBinderMap and
// internal::PopulateBinderMapWithContext).
//
// By default, BrowserInterfaceBrokerImpl runs the binder that was registered
// for a given interface when the interface is requested. However, in some cases
// such as prerendering pages, it may be desirable to defer running the binder,
// or take another action. Setting a non-null `MojoBinderPolicyApplier` enables
// this behavior.
//
// Note: BrowserInterfaceBrokerImpl will eventually replace the usage of
// InterfaceProvider and browser manifests, as well as DocumentInterfaceBroker.
