I think this was likely a non-portable regex that was being used to match the function signatures,
causing it to miss anything with an internal "s" in the function name. Here's a quick fix for the release branch:

(This sort of thing will become easier to work with, soon, as we'll have an automated doc build which can be examined for each MR.)

P.S. nice email address!

That isn't expected - thanks for pointing this out! I can reproduce locally so will take a look.
