Indeed, open blocks cannot be nested [1]. But, the first open block is not

We've run in this before, but I don't think we ever came up with a
satisfactory general solution.

You can find one more case with:

  cd Documentation
  ./doc-diff --from-asciidoc --to-asciidoctor HEAD HEAD

and searching in the pager for:

  /^\+[ ]+\+

which shows added lines starting with "+". The other one is in the
pretty-formats %(decorate) description, which is included in a few
places.

There are some other hits for ASCII art, some of which I think are
mis-rendered. But that's a separate problem. :)
