STR:

1. Open this search results page: https://search.brave.com/search?q=a

Actual results:

The Reader View button is visible in the Firefox address bar.

Expected results:

The Reader View button is not visible in the Firefox address bar.

I believe this is an issue in the Readability library, erroneously calculating that the page is an article.
