Preserve videos in paragraphs

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch @mozilla/readability@0.5.0 for the project I'm working on.

Here is the diff that solved my problem:

     // Remove extra paragraphs
     this._removeNodes(this._getAllNodesWithTag(articleContent, ["p"]), function (paragraph) {
       var imgCount = paragraph.getElementsByTagName("img").length;
+      var videoCount = paragraph.getElementsByTagName("video").length;
       var embedCount = paragraph.getElementsByTagName("embed").length;
       var objectCount = paragraph.getElementsByTagName("object").length;
       // At this point, nasty iframes have been removed, only remain embedded video ones.
       var iframeCount = paragraph.getElementsByTagName("iframe").length;
-      var totalCount = imgCount + embedCount + objectCount + iframeCount;
+      var totalCount = imgCount + videoCount + embedCount + objectCount + iframeCount;
 
       return totalCount === 0 && !this._getInnerText(paragraph, false);
     });

If I don't apply this change, the video on this website will be removed.

Do you think we can open a PR to fix it?

Start in Readability.js at the “Remove extra paragraphs” logic shown in the issue, and compare it with the supplied patch. Verify the article extraction behavior on the linked Shortwave page and confirm that videos inside paragraphs are preserved rather than removed.
