Yes, this is a new side effect of making ESS more reliable for multiple
processes interface.

This is a very good idea. I will try to add this feature these days. 

In ESS buffers this problem should never occur. If it does, it is a bug.

For other modes, such as org-mode a permanent solution for you would be
to (setq ess-dialect "R") in org-mode-hook.

I will look into this. It seems that ess-remote is not keeping up with
recent changes.
