Bugzilla

The current scrolling behaviour is not great anyway especially on a long page due to smooth scroll. I’ll add a workaround to Bugzilla to temporarily disable the smooth scrolling when the Home/End key is pressed, like this:

```js
document.querySelector('#bugzilla-body').addEventListener('keydown', event => { 
  const { target, key, metaKey, ctrlKey } = event;
  const accel = event.metaKey || event.ctrlKey;
  const to_top = event.key === 'Home' || (event.key === 'ArrowUp' && accel);
  const to_bottom = event.key === 'End' || (event.key === 'ArrowDown' && accel);

  if (to_top || to_bottom) {
    event.preventDefault();
    target.style.setProperty('scroll-behavior', 'auto');
    target.scrollTop = to_top ? 0 : target.scrollHeight;
    target.style.setProperty('scroll-behavior', 'smooth');
  }
});
```

This skips the comments and jumps to the top/bottom of the page immediately.
