One year later, I took a look at this problem again, and realized what the problem was:
* There was a teeny tiny, empty MIDI item, less than one tick in length and practically invisible, overlaid over the long MIDI item at the start of the region.
* The project's item mix behavior was set to "Enclosed items replace the enclosing item".

The tiny MIDI item therefore blocked the note-on events from playing, if playback started precisely at the start of the region.

If playback started a little later, beyond the tiny MIDI item but before the note ends, REAPER would chase the note-ons and play them.

(I therefore removed the second part of the thread title, "2) Note does not play when playback starts at grid".)
