// General security note on the implementation pattern of this interface. In Dev10 it was chosen
// to expose the interface implementation for overriding to customers. We did so by keeping the
// explicit interface implementations (that do have the property of being hidden from the public
// contract, which limits IntelliSense on derived types like WebBrowser) while sticking protected
// virtuals next to them. Those virtuals contain our base implementation, while the explicit
// interface implementation methods do call trivially into the virtuals.
//
// This comment outlines the security rationale applied to those methods.
//
// <SecurityNote Name="IKeyboardInputSink_Implementation">
// The security attributes on the virtual methods within this region mirror the corresponding
// IKeyboardInputSink methods; customers can override those methods, so we insert a LinkDemand
// to encourage them to have a LinkDemand too (via FxCop).
