Topic: :fullscreen CSS pseudo class
Problem: The button background color is not changing when toggling between fullscreen and none-fullscreen using F11 and Esc.
https://jsfiddle.net/og9eLsav/
Code mentioned in https://developer.mozilla.org/en-US/docs/Web/CSS/:fullscreen

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Document</title>
    <style>
        #fs-toggle:fullscreen {
        background-color: #faa;
      }

      #fs-toggle:not(:fullscreen) {
        background-color: #afa;
      }
    </style>
  </head>
  <body>
    <h1>MDN Web Docs Demo: :fullscreen pseudo-class</h1>

    <p>
      This demo uses the <code>:fullscreen</code> pseudo-class to automatically
      change the style of a button used to toggle fullscreen mode on and off,
      entirely using CSS.
    </p>

    <button id="fs-toggle">Toggle Fullscreen</button>
  </body>
</html>

Here is a list of CSS pseudo-classes. I am wondering if there is an easy way to identify which ones require JS to work, like the case with :fullscreen. https://developer.mozilla.org/en-US/docs/Web/CSS/Pseudo-classes

I was very much expecting https://github.com/whatwg/html/pull/9885 to be spam, but it seems legit

seems like an obvious hacktoberfest play to me, but if it's legit, ¯\_(ツ)_/¯

Ooh, I forgot what month it was. Bah.

Oh well.

But at least it's a reasonable change and not just randomly removing things.
