The smooth scrolling in general seems a little off. If i have a long page with a lot of stories, clicking on each one jumps to the top of the page and slowly scrolls down, and the story i'm scrolling do ends up at the bottom of the page.

I think these settings need some adjustment:

This feels better, but doesn't quite scroll the heading into view at the top of the page.

element.scrollIntoView({
  behavior: 'auto',
  block: "start",
  inline: 'nearest'
});

Is this the intended behavior? I'm curious whether I'm using the addon wrong, or if the intended behavior is to scroll to bottom? Since the focus of the addon is for docs, it doesn't seem like something that should be intentional, since the ideal consumption would be top to bottom.
