As per the spec wordings,
`The [getIterator(HTML.Tag t)](https://docs.oracle.com/en/java/javase/20/docs/api/java.desktop/javax/swing/text/html/HTMLDocument.html#getIterator(javax.swing.text.html.HTML.Tag)) method can also be used for finding all occurrences of the specified HTML tag in the document.`

which I think is what we get with the fix an Iterator object with next block tag
