Readability returns the longest html object as the most plausible if an article's header is longer than actual content
When reader mode (or the standalone readability library) encounters an article on a page where a header has greater content length than the actual article or main content, then the object returned by readability will have members `content` and `textContent` matching the article header and not the actual article. This results in reader mode displaying incorrect content for a given article:
An example Blogger post where readability / reader mode work as expected: https://gnosticesotericstudyworkaids.blogspot.com/2023/11/learning-to-let-go-of-small-details-4902.html
An example Blogger page where readability / reader mode do not correctly return the article's main content: https://gnosticesotericstudyworkaids.blogspot.com/2023/11/really-understand-ego-or-anything-when.html
It appears that the logic in `_grabArtcile` is failing to nominate the actual article content as the most plausible: https://github.com/mozilla/readability/blob/main/Readability.js#L876
