[External] Suppressed "graphical parameter" warnings reviving themselves magically

Warnings are not "reviving themselves magically". Try resizing the
window a few times and hitting return in the REPL. That should give
you a hint on what is going on.

Best,

What's going on here?

$ R --vanilla --quiet
plot.new(); suppressWarnings({ points(0, 0, foo = TRUE) })
NULL
NULL
Warning messages:
1: "foo" is not a graphical parameter
2: "foo" is not a graphical parameter

Note how the warnings are revived in that second "NULL" call.  I can
reproduce this in R 4.4.3 and R-devel (2025-03-19 r88003). This might
be specific to "graphical parameter" warnings, because it won't happen
with, say, suppressWarnings({ log(-1) }).

It also doesn't appear if I call split up the first call into to
different REPL calls;

$ R --vanilla --quiet
plot.new()
suppressWarnings({ points(0, 0, foo = TRUE) })
NULL
NULL

PS. I thought I had sent this many months ago, but I just now found
this message in my draft folder, so now I'm not sure. Sorry, if this
is a duplicate.
