Created an isolated test case: https://github.com/jaymakes11/ssc-reproduce-tap-bug

Created a demo video in that repos README (watch with video's sound turned ON to hear the taps).

I was able to reproduce, the bug seems to be that the first tap on something that should be tappable isn't getting recognized, but all subsequent taps are. I'll look into this more.

Just a note here that I'm somewhat consistently seeing it happen on the same element (without taping something else in between taps), though I don't think this was shown in my demo video.

what's also a bit interesting is that tap on body always responds.

document.body.addEventListener('click', function() {
  console.log('BODY TAP') // tap is reliable
})

UPDATE: It also looks like the pointer down event fires reliably on all taps.

incrementButton.addEventListener('pointerdown', function() {
  console.log('BUTTON TAP') // tap is reliable
})
