This method doesn't override a method from WebPlugin, so it doesn't need to be
virtual, and should be named in the chromium style (HasFocus()) and moved
outside of the block of WebPlugin methods. After ReplayReceivedData seems like a
good place for it.

Remove this function as no need after merging.
