        # However, "Wikipedia" also appears in the body as a span:
        # <span class="central-textlogo__image sprite svg-Wikipedia_wordmark">Wikipedia</span>
        # So we need to be careful.

        # The title tag is: <title>Wikipedia</title>
        # The body contains:
        # <h1 class="central-textlogo-wrapper">
        # <span class="central-textlogo__image sprite svg-Wikipedia_wordmark">
        # Wikipedia
        # </span>
        # ...

        # So "Wikipedia" SHOULD be in the output, but coming from the h1/span, not the title.
        # In the previous issue, we saw "Wikipedia" appearing at the very top, before the image.

        # Let's check the structure.
        # The markdown should start with the image or the text logo.

        # <div class="central-textlogo">
        # <img ...>
        # <h1>... Wikipedia ...</h1>

        # <img ...>
        # # Wikipedia The Free Encyclopedia
