[ESS] Emacs27 and options("prompt") interaction ?

Following Zeileis and Kleiber in their 'AER' book, I have had

        prompt="R> ",                           # AER page vii

as an value to options() in .Rprofile for a number of years.

Emacs27 is still not mainstreamed in Debian and Ubuntu, but on one machine I
installed it from PPAs as I was curious about the new rendering engine.
Looks like it behaves well, font rendering is nice -- but the above creates a
'jumpy' cursor that settles if I revert to "> ".

Now, as we all do, I have a lot of other settings in my dot profile that
_could_ be causing this. But has anybody else seen this?
