Got a bit further:

I forgot to adjust the sample->loopstart and sample->loopend values and
I am not even sure if they make sense at all for compressed samples. If
you wipe away this whole block in src/sfloader/fluid_defsfont.c that my
patch adds to fluid_sample_import_sfont()

    /* loop is fowled?? (cluck cluck :) */
    if (sample->loopend > sample->end ||
        sample->loopstart >= sample->loopend ||
        sample->loopstart <= sample->start)
    {
      /* can pad loop by 8 samples and ensure at least 4 for loop (2*8+4) */
      if ((sample->end - sample->start) >= 20)
      {
        sample->loopstart = sample->start + 8;
        sample->loopend = sample->end - 8;
      }
      else /* loop is fowled, sample is tiny (can't pad 8 samples) */
      {
        sample->loopstart = sample->start + 1;
        sample->loopend = sample->end - 1;
      }
    }

and replace it with a simple

    sample->loopstart = sample->loopend = 0;

the MIDI plays back as expected.
