This is visual debugger. If you are already in *R* buffer the focus is
never switched to the code buffer. The code buffer is only popped up and
the currently debugged line highlighted. The current buffer should
always stay *R*.

If this doesn't happen for you, that means it is a bug or some
configuration of yours that interferes with how ESS views the debugging.

It is not new, it always appears there whenever you have source
references in your code.
