Mastodon: clear notification badge in title

Strips the unread count prefix from the tab title so the browser tab icon stays clean.

Code to copy

// Remove the favicon notification badge by resetting the document title
(function () {
  function strip() {
    var t = document.title || '';
    var clean = t.replace(/^\(\d+\)\s*/, '');
    if (clean !== t) { document.title = clean; }
  }
  strip();
  var obs = new MutationObserver(strip);
  var target = document.querySelector('title');
  if (target) { obs.observe(target, { childList: true, characterData: true, subtree: true }); }
  setInterval(strip, 2000);
})();
