Release 20220608.1

• Fix bugs in CSS tokenization
• Fix deocding of HTML character references that lack semicolons
  like &para in HTML attribute values that affected
  URL query parameters.

Changes how we avoid problems with special tags inside <select> elements. Instead of complicating the rendering of <style> elements in all cases, now we just close special elements when they are embedded in <select> elements so no text under a <select> is interpreted as anything other than PCDATA.

Improves SVG and MathML support.
Now policies don't lower-case element and attribute names that are defined in either the SVG or MathML schemas.

Be aware that SVG's <textArea> is now distinct from HTML's <textarea>.

• Recognize HTML entity names added in the last few years. Now &name; will work consistently.

• Strip ZWNJ from MacOS and iOS crashing text sequences
