I don't think it makes sense to do this on a remote frame.

The topmost frame will never be remote. A remote frame represents a frame in the
local frame tree that's running in another process; it doesn't have any nodes or
renderers, this is just a way for local frames to post messages to it.

I'll still need to implement it, but I can make it a noop (as many other things
in the implementation are).

If this doesn't make sense to implement on remote frames, should the interface
method be moved to WebLocalFrame.h instead?
