No love for the <plaintext> tag? "The <plaintext> HTML element renders everything following the start tag as raw text, ignoring any following HTML. There is no closing tag, since everything after it is considered raw text." - it's my favorite obscure deprecated HTML tag.
Fun fact: this is very close but slightly inaccurate. I used to think this is how it worked before scrutinizing a rule in the HTML tree-building specification.
The tag leads the parser to interpret everything following it as character data, but doesn’t impact rendering. In these cases, if there are active formatting elements that would normally be reconstructed, they will after the PLAINTEXT tag as well. It’s quite unexpected.
