Quite sure.  But it doesn't matter much: what matters is that the
offending string, "* foo\nbar", comes from the call to
gui-selection-value.  And once it gets into the kill-ring, you cannot
undo that.  org-copy-visible only handles what gets put into the kill
ring when you invoke the command, it doesn't do anything what happens
about invisible text when you yank.

Yes, because without that, yanking doesn't consult the primary
selection, it only consults the clipboard.
