I cannot reproduce this (but I'm not on Darwin).

Is this in "emacs -Q"?  If not, please try in "emacs -Q", maybe it's
some customization you have there.  (I'm confused by your mentioning
of "refreshing with g", which seems to hint on Dired?)

If this happens in "emacs -Q", it might be specific to Darwin.  In any
case, if you can try this in a later version, it will help, in case we
already fixed this even on Darwin.

Thanks.
