 Fun bug I found and tracked down with @pento:

 1. Set an element's content via innerHTML to an emoji character
 2. Observe the content has been replaced with Twemoji correctly
 3. Set the element's content to the exact same value again
 4. Observe the content has been ''not'' replaced

 You can try this on any page our Twemoji replacement is loaded on:
 {{{
 window.setInterval(function () { document.querySelector('div').innerHTML =
 '\ud83d\ude3d'; }, 500);
 }}}
