Disambiguation Control v8 seems to be doing the trick for this particular situation, without having to code anything extra other than adding the extension. However, it appears that, to remove all potential issues, I should use the “Use no parser suggestions.” option in the extension. Unfortunately, although the extension by itself is working fine in 6L38, “Use no parser suggestions.” is always causing a translating the source error. I would assume that the discussion of that is better off elsewhere, though.
Thanks.
