What's Changed

This release aligns HTML parsing with the WHATWG spec Almost all changes are to HTML mode only — XML mode is unaffected unless noted.

Raw-text & RCDATA tags

• <iframe>, <noembed>, <noframes>, and <plaintext> are now raw-text tags, their content is no longer parsed as HTML
• <textarea> now decodes entities like <title> already did
• Self-closing <script/>, <style/>, etc. now enter their raw-text state (the / is ignored per spec) unless recognizeSelfClosing is enabled

SVG & MathML

• Tag names inside <svg> are case-adjusted per spec (foreignObject, clipPath, etc.)
• CDATA sections inside foreign content are treated as text
• Special-tag detection is disabled inside foreign content
• Stray </svg> / </math> no longer corrupt the parser's context tracking

Comments & declarations

• <!-->, <!--->, <!->, <!> now parse as valid comments per spec
• <?…> and non-DOCTYPE <!…> in HTML mode emit bogus comments instead of being silently dropped
• <!DOCTYPEhtml> (no space) is recognized as a DOCTYPE
• Unclosed comments, <!DOCTYPE, <?…, <![CDATA[… at EOF emit the correct token type

Implicit open/close

• <h1>–<h6> implicitly close other headings
• <a> closes a previous <a>
• Nested <form> is ignored when one is already open
• <image> is rewritten to <img> outside foreign content
• </> is silently ignored instead of emitted as text

Other fixes

• Fixed reset() not clearing attribute state, which could leak data across parseComplete() calls
