Help troubleshooting what's stripped out

[avk]

Thanks for your work on this neat gem.

Running readability on the HTML from https://100wordstory.org/submit/, I expected more markup to remain than readability leaves intact.

Expected

Observed

In the screenshot above, the following content is stripped out:

1. the red "Submit" heading:

<h1 class="titles">
  <a href="https://100wordstory.org/submit/" rel="bookmark" title="SubmitPermanent Link to ">Submit</a>
</h1>

2. the red "Submissions are now open through January 9, 2024" and "Submit!" headings and links:

<h2 style="text-align: center;"><a href="https://100wordstory.submittable.com/submit">Submissions are now open through January 9, 2024!</a></h2>
<h2 style="text-align: center;"><a href="https://100wordstory.submittable.com/submit">Submit!</a></h2>

Turning on debug: true doesn't seem to cite why these items are missing:

					<p>100 words for your story … no more or no less. Tell a story, pen a slice of your memoir, or try your hand at an essay.</p>
<p>You get 100 words—exactly 100 words—which is both the pain and the pleasure here. It’s short, you tell yourself. You could write 100 words at a bus stop, on your lunch break, in your sleep. But with 100 words you must tell the whole story in its entirety, so it holds together like a perfect little doll house. (Your title is not part of the 100 words.)</p>
<p>Please include a short bio (25 words, max!) with your submission. Also, did we say exactly 100 words? We weren’t kidding! We count words according to Microsoft Word’s word-count tally. Also, make friends with your spell-check, or have a friend proofread your story.</p>
<p>We currently charge a $2 submission fee, the minimum in order to cover the costs of the submission system.</p>

Any ideas on how to broaden or include this content?

[avk]

I think I've traced this particular effect to this part of #sanitize:

      node.css("h1, h2, h3, h4, h5, h6").each do |header|
        header.remove if class_weight(header) < 0 || get_link_density(header) > 0.33
      end

What's the thinking behind link density, especially applied to headings? Is there a way to customize or tune this?

This is the same code as was in the original readability.js from which this was ported, I think. You could parameterize it if you want to make it more flexible.
