Extremely simple polyfill for hanging-punctuation in Chrome

hanging-punctuation-polyfill.js

/*
I only really use hanging-punctuation: first and only expect it to
work in blockquotes, which makes the usage extremely simple. And yet
for some reason I've never done a simple polyfill. Now I have.
*/
(function() {
  if ( !CSS.supports("hanging-punctuation", "first") ) {
    document.querySelectorAll("p").forEach(e => { if ( e.innerText.trim()[0] == "“" ) { e.style.textIndent = "-0.725ch"; } });
