(which is obviously not realistic, but just for demonstration purposes) wasn't enough in every case. It turned out that any for element on which I had handled click, double tapping on it would cause a nearly irreversible zoom-in, completely ignoring the touch-action setting. But if I called preventDefault() in the click handler, it would not zoom. So, doing this at the document level so far seems to be enough, so that I don't have to do it every time I handle click.
