I should have know better than to copy as I did from the source code 
without analyzing it sufficiently! In typo-spa.mkiv I found:

    \setupcharacterspacing [frenchpunctuation] ["003A] [\c!left
    =.25,\c!alternative=1] % : ...

I see (now) that the space disappears when the \c!left macro is 
processed. Mea culpa. I owe you a beer.

        Playing with define/setup/set characterspacing, I have come
        across some odd, perhaps buggy, behavior. This applies to both
        MkIV 2020.11.19 11:23 and LMTX 2020.11.19 11:28.

        The problem is that character spacing is not effected for the
        left side of the comma character. It is handled as expected for
        other characters that I have tested, but I have not performed
        extensive tests.
