I’ve attached a patch.
It also fixes a niggle I had in that you could force the frame to use
a dark theme, or an aqua theme, but not the system default even though
Emacs would launch with the system default. The documentation was also
wrong in that it described the light theme as the system default, even
though it may not have been.
I’m not sure if this is too big a change for emacs 27 at this stage,
as it’s not entirely fixing bugs, although I’d argue it’s completing a
feature that is incomplete in Emacs 26.
